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 :
- A directed parallel to the plane of plate and in upward direction
- B directed parallel to the plane of plate and in downward direction
- C directed perpendicular to the plane of plate and towards the plate
- D directed perpendicular to the plane of plate and away from the plate
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…
