What happens when the leaves of an electroscope are spread apart?

What happens when the leaves of an electroscope are spread apart?

The leaves in an electroscope spread apart when an electrical charge is brought close to or in contact with the conductor. This happens because the same charge, whether positive or negative, will be received by the leaves, and in turn will cause their repulsion (spreading apart).

Why the leaves on this metal leaf electroscope are spread apart?

The leaves spread apart because the excess electrons in one leaf repel the excess electrons in the other leaf.

Why the leaves of gold leaf electroscope repel each other and spread apart?

If the charge is positive, electrons in the metal of the electroscope are attracted to the charge and move upward out of the leaves. This causes the leaves to have a temporary positive charge and because like charges repel, the leaves separate.

Why electroscope leaves show divergence What does it mean?

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.

What does the amount of spreading of the leaves of the electroscope signify about the charges in the leaves?

By direct contact of charging by induction, use light weight gold leaves within the electroscope to indicate the relative amount an object is charged. Leaves will spread out more and more as they gain more and more charge, whether positively or negatively charged.

When a rod is brought near a neutral electroscope the leaves diverge Which statement best describes the charge on the rod?

Q. When a rod is brought near a neutral electroscope, the leaves diverge. Which statement best describes the charge on the rod? It must be positive.

When a rod is brought near a neutral electroscope the leaves spread apart Which statement best describes the charge on the rod?

When a rod is brought near a neutral electroscope, the leaves diverge. Which statement best describes the charge on the rod? It must be positive.

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

Let’s see how Gold Leaf electroscope functions. When a charged object, say positively charged, is brought near the electroscope; negative charges move towards the disc leaving the leaves positively charged. This positive charge makes the leaves diverge as like charges repel each other.

Why do the diverged leaves of an electroscope fall back on touching the top of the metal rod with hand?

When we touch the electroscope with hand when the leaves are diverged, the charges travel through our body into the ground and thus the leaves fall back into their original position. This phenomenon is called Earthing.

What will happen to the leaves of an electroscope if a positively charged body is brought near?

A charged body is brought near a positively charged gold leaf electroscope. The divergence of its leaves increases.

Why do leaves diverge?

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 will happen to the leaves of an electroscope if a positively charged body is brought near a an uncharged electroscope and B positively charged electroscope?

Solution : (a) Diverge (b) Will diverge further (c ) First converge and then again may diverge.
