What will happen to the leaves of a negatively charged electroscope?

When a negatively charged object is brought near an electroscope the charge will induce a positive charge on the leaves. So nothing should happen.

What happens when a negatively charged rod touches an electroscope?

When the negatively-charged rod is brought close to the electroscope, positive charges are attracted to it and negative charges are repelled away from it.

What will be the charge on the leaves of an electroscope if you bring a negative rod near the end of its metal cap?

Hence, the charge on the metal cap is negative and the charge on the leaves of electroscope is positive.

What would happen to the leaves of an electroscope when a negatively charged object is brought in contact with the rod of electroscope?

If you bring a negative object near the electroscope, the electrons in the scope will be repelled toward the leaves, balancing the charge. The leaves will move toward each other.

What are the leaves made of in a gold leaf electroscope?

Gold leaf electroscope has two gold leafs suspended from a metal(usually brass) stem in a vacuumed glass jar and connected to a metal cap. The glass is grounded with the help of a metal foil to make it uncharged.

Why is gold used in the gold leaf electroscope?

It does not corrode easily and can be made into very thin sheets.

Why do the leaves remain separated after the rod has touched the ball and been removed?

Move the rod away and the leaves will collapse. Again move the rod toward the ball, but this time touch it. Electrons will flow from the rod to the leaves, and the leaves will move apart and remain even further apart after the rod has been removed. You have charged the electroscope by conduction.

Why do the leaves of an electroscope spread apart when a charged object touches the metal knob?

Similar to the results of a negatively charged rod, if a positively charged rod is brought near the knob of a neutral electroscope, it will attract some electrons up from the leaves onto the knob. That process causes both of the leaves to be positively charged (excess protons), and the leaves will diverge.

When negatively charged rod is brought near the cap of a gold leaf electroscope whose case is earthed then?

When a negatively charged body is brought near the cap of a gold leaf electroscope whose case is earthed,then the electrons near the brass disc of the electroscope gets repelled and so they move from the brass disc to the leaves .

What happens when a positively charged object is brought near a negatively charged object?

When two positively charged objects are brought near each other, a similar repulsive force is produced. When a negatively charged object is brought near a positively charged object, an attractive force is produced.

When an object is placed near a negatively charged electroscope the leaves of the electroscope diverge farther Which statement about the object is true?

When an object is placed near a negatively charged electroscope, the leaves of the electroscope diverge farther. Which statement about the object is true? It must be neutral.

Why did the leaves remain separated after you removed your finger and the rod use the idea of ground in your description?

The negative charge of the rod will repel electrons away from the electroscope and they will flow into your body. When you remove your hand and the charged rod, the leaves spread apart, indicating a positive charge has been achieved due to the loss of electrons.

How can a gold leaf electroscope be negatively charged by using the induction process?

In the induction process of charging, a charged object is brought near to but not touching the electroscope. The presence of the charged object above the plate of the electroscope, induces electrons within the electroscope to move accordingly.

When the disc of a gold leaf electroscope is touched with a negatively charged body what is the nature of charge developed on the gold leaves?

Hence, When the disc of GLE is touched with positively charged glass rod the charge on the leaves of GLE is positive.

What is the principle of gold leaf electroscope?

A gold-leaf electroscope is used for detecting electric charge present in a body and identifying its polarity. Its operation is based on the principle of electrostatic induction and like charge repulsion.

How does gold leaf electroscope detect charge?

To detect the presence or absence of charge on a body, we bring the body close to the gold leaf electroscope and touch it with the cap of the device. If the body has charge, then the two leaves of the electroscope also get similarly charged.

Why do the leaves of a gold leaf electroscope diverge when a charged body is brought in contact with its disc do they always diverge to the same extent?

Answer. The leaves of an electroscope diverge because when an object is touched on the metal disc, the charge travels through the metal rod to the leaves. Since LIKE charges repel, the charge travels till the leaves and the open up as both the leaves have like chargeS.

Why do the leaves spread apart when negatively or positively charged?

When a positively charged object is brought near the knob, the electrons in the leaves move towards the other end being attracted by the rod. Thus the leaves lack electrons and both become positively charged and thus push each other apart.

What happens to the leaf of a gold leaf electroscope when the same charge is put on it?

Both the gold leaves will have same charge and hence as a result they will repel and diverge. The degree of divergence is an indicator of the amount of charge i.e., more the charge, more will be the divergence.

When a negatively charged rod is brought near but does not touch the initially?

When a negatively charged rod is brought near, but does not touch, the initially uncharged electroscope shown above, the leaves spring apart (I). When the electroscope is then touched with a finger, the leaves collapse (II).

When a positively charged rod is brought near the cap of a gold leaf Electroscope?

Solution. When a positively charged rod is brought near the positively charged cap then, the positive charge on the cap will spread over because of repulsion and some of them will reach the leaves. Now, the leaves will have the same positive charge, they will repel each other and hence, leaves will diverge.

What happens when a negatively charged object a is brought near a neutral object be?

When you bring a negatively charged object close to a neutral pith ball, it creates a positive charge (i.e. opposite of negative) on the portion of pith ball nearer the negatively charged object and negative charge on the farthest portion of pith ball.

What happens when a neutral object and a negatively charged objects are brought together?

Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

When a negatively charged rod is brought near the cap of a gold leaf electroscope whose case is earthed then?

Why did the leaves of the electroscope diverge when the negatively charged rod touched it?

The greater the charge, the farther apart they move. When a positively charged object is brought near the knob, the electrons in the leaves move towards the other end being attracted by the rod. Thus the leaves lack electrons and both become positively charged and thus push each other apart.

Why is a gold leaf electroscope negatively charged?

8) This charge travels down (due to like charges repel) and the gold leaf starts becoming neutral again. 9) When the rod is removed the excessive negative charges spread out and cause the gold leaf to possess a greater amount of negative charge so they deflect (repel again) This makes the gold leaf electroscope negatively charged.

What happens when a negatively charged object is brought near electroscope?

When a negatively charged object is brought near an electroscope the charge will induce a positive charge on the leaves.

What happens when X-ray beam falls on gold leaf electroscope?

Since, the gold leaf electroscope  is  negatively charged , when the beam of x-ray is allowed to fall upon the electroscope, since x-rays are the ionising radiations, it will ionise the air surrounding gold leaf electroscope. As a result, negatively charged leaves would attract the positive ions from the surrounding air and would then discharge.

How does an electroscope separate leaves?

The electrons in the electroscope, which are mobile (since the electroscope is probably made out of a metal conductor), are repelled by the negatively charged rod, and migrate to the leaves, therefore separating them. The picture below depicts this well.
