Question

A body is brought near a negatively charged gold leaf electroscope. If the divergence of leaves remains unchanged, state the kind of charge on body in this case.

• A. positive
• B. Negative
• C. no charge
• D. cant say

Answer 1

The correct option is C no charge

When we touch the body to be tested with the metal disc of an electroscope, the leaves of an electroscope open up (diverge), that is, the body is charged. If the leaves remain unaffected, the body has no charge.
In this case, the divergence of leaves remains unchanged.
Hence, the body has got no charge.
