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

Answer: (B)

Charge will be induce 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.
