Question

An ebonite rod rubbed with fur is brought near a piece of silk rubbed with a glass rod. What will you observe?

• A. Attraction
• B. Repulsion
• C. No visible change
• D. First attraction, then repulsion

Answer 1

The correct option is B

Repulsion

Explanation for the correct option:

1. When the ebonite rod is rubbed with fur, it gets negatively charged.
2. Similarly, when silk is rubbed with a glass rod, the silk cloth becomes negatively charged.

Since, both the ebonite rod and the silk cloth are negatively charged, they will repel each other when brought close. So, the correct answer is option (B) - Repulsion.
