Question

What happens when an ebonite rod is rubbed with fur?

• A. electrons flow from fur to ebonite rod.
• B. the protons flow from fur to the ebonite rod.
• C. the ebonite rod becomes a positively charged body.
• D. both (b) and (c)

Answer 1

The correct option is A

electrons flow from fur to ebonite rod.

The explanation for the correct option:

Option A

1. Fur is having more free electrons than the ebonite rod and is also a conductor of electricity. Ebonite rod is made up of vulcanized rubber.
2. So it is not an electrical conductor and has fewer free electrons.
3. So when fur is rubbed with an ebonite rod, more free electrons from fur will come out and flow to the ebonite rod.

The explanation for incorrect options:
Option B

The protons do not flow anywhere it resides in the nucleus, so this option is ruled out.

Option C
Ebonite does not become a negatively charged body. so this option is also incorrect.

So, the correct option will be (a) electrons flow from fur to ebonite rod.
