Question

If the metal clip used in the electroscope is replaced by an ebonite rod and a charged body is brought in contact with it, will there be any effect on the aluminum strips? Explain.

Answer 1

Electroscope:

1. An electroscope is a device that is used to determine whether an object is charged or not.
2. It consists of two aluminium strips that are positioned close to each other.
3. When charges are applied to strips, they repel each other and create a big gap between themselves.

Explanation:

1. There will be no repulsive action between those two aluminium strips.
2. It is because of the ebonite. It is an insulator, the charged body can not transfer any charge to it.
3. Hence, there won't be any charge on the aluminium strips, and the strips will not go far or repel each other.

Hence, Electroscope will not work, if ebonite is used.
