A point charge \(-q\) is placed at a distance \(x\) from an isolated conducting plane. The electric field at any point \(P\) on the other side of the plane is directed
A point charge \(-q\) is placed at a distance \(x\) from an isolated conducting plane. The electric field at any point \(P\) on the other side of the plane is directed
Show Hint
Electric field at conductor surface is always normal to it.

- radially away from the point charge
- towards the plane perpendicularly
- radially towards the point charge
- away from the plane perpendicularly
- parallel to the surface of the conducting plane
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Electric field near conductor is always perpendicular to surface.
Step 1: Field direction.
• Field lines terminate on conductor
• Direction is normal to surface
Step 2: Conclusion.
Field is towards the plane perpendicularly.
