Q. 24.7( 10 Votes )

A metallic particle having no net charge is placed near a finite metal plate carrying a positive charge. The electric force on the particle will be
A. towards the plate

B. away from the plate

C. parallel to the plate

D. zero

Answer :

The metal plate carries a positive charge; it will induce an equal and opposite negative charge on the metallic particle following the law of electric induction. Hence, since electric field lines move from negative charge to positive charge, the force will pull the particle towards the plate.

Thus, option A is the correct option.
