Question

If a charged conductor is enclosed by a hollow charged conducting shell (assumed concentric and spherical in shape), and they are connected by a conducting wire, then which of the following statement (s) would be correct?

• A. Potential difference between two conductors becomes zero.
• B. If charge on inner conductor is $q$ and on outer conductor is $2 q$, then finally charge on outer conductor will be $3 q$.
• C. The charge on the inner conductor is not totally transferred to the outer conductor.
• D. If charge on the inner conductor is $q$ and charge on the outer conductor is zero, then finally charge on each conductor will be $q / 2$.

Answer 1

Answer: (A), (B)

This question is based on the working principal of a van de Graaff generator.
