A point charge -Q is placed at a small distance r from an isolated conducting plate. The direction of the electric field at a point A on the other side of the plane at the same distances r is :

  1. A directed parallel to the plane of plate and in upward direction
  2. B directed parallel to the plane of plate and in downward direction
  3. C directed perpendicular to the plane of plate and towards the plate
  4. D directed perpendicular to the plane of plate and away from the plate
Verified Solution

Answer & Solution

Correct Answer

(C) directed perpendicular to the plane of plate and towards the plate

Step-by-step Solution

Detailed explanation

The electric field outside a conductor is always perpendicular to its surface. A negative point charge -Q induces positive charges on the near side and negative charges on the far side of an isolated conducting plate. At point A on the far side, the electric field due to the…
