A point charge `+q` is placed at a distance `d` from an isolated conducting plane. The field at a point `P` on the other side of plane is

Options

A. directed perpendicular to the plane and away from the plane.
B. directed perpendicular to the plane but towards the plane.
C. directed radially away from the point charge
D. directed radially towards the point charge.

Answer

A

Explanation

When a point positive charge brought near an isolated conducting plane, some negative charge developes on the surface of the plane towards the charge and an equal positive charge developes on opposite side of the plane. This process is called charging by induction.
