Question

An ebonite rod rubbed with fur is brought near the disc of a negatively charged gold-leaf electroscope. What will happen to the divergence of the gold leaves?

• A. It will increase.
• B. It will decrease.
• C. It will not change.
• D. Cannot be predicted.

Answer 1

The correct option is A

It will increase.

Explanation for the correct option: (A)

1. When an ebonite rod is rubbed with fur, it gets negatively charged.
2. So, when this negatively charged ebonite rod is brought near the disc of a negatively charged gold-leaf electroscope, the leaves become more negatively charged and hence, diverge more.

Thus, the divergence between the leaves will increase.
