Question

An uncharged conductor $A$ is brought near a positively charged conductor B. Then :

• A. the charge on B will increase, but the potential of B will not change
• B. the charge on B will not change, but the potential of B will decrease
• C. the charge on B will decrease, but the potential of B will not change
• D. the charge on B will not change, but the potential of B will increase

Answer 1

The correct option is B the charge on B will not change, but the potential of B will decrease

Charge will be induced on A, but total charge on A will remain zero. Negative charge of A will be more closer to B than positive charge on A. So potential of B will decrease.
Hence A,C,D are wrong and B is correct
