Question

A large nonconducting sheet $M$ is given a uniform charge density. Two uncharged small metal rods $A$ and $B$ are placed near the sheet as shown in figure. Then

• A. $M$ attracts $A$
• B. $M$ attracts $B$
• C. $A$ attracts $B$
• D. All of the above

Answer 1

The correct option is D All of the above

By electrostatic induction the charge will appear on A and B due to charged sheet M. There may be two cases- when M is positively charged and when it is negatively charged.(shown in fig). In the figure all attract each other.
