    1. The problem statement, all variables and given/known data
    A large conducting sheet M is given a uniform charge density. Two uncharged small metal rods A and B are placed near the sheet on one side. Then
    a)M attracts A
    b)M attracts B
    c)A attracts B
    d)B attracts A

    2. Relevant equations

    3. The attempt at a solution
    An electric field will be set up by the sheet but A and B are neutral. So how can it attract them?

    Good Morning Utkarshakash,

    Have a look at "electrostatic induction".

    OK so if I assume the sheet to be +vely charged it will induce a -ve charge on the side of block A near to the sheet and +ve charge on the other end. Block A will then induce -ve charge on the side of B near to A and +ve charge to the other side. Am I right?
