Question

A positive charge q is placed in front of a conducting solid
cube at a distance d from its centre. Find the electric field at the
centre of the cube due to the charges appearing on its suface.​

Answer 1

Answer:

The electric field at the centre of cube is 0 due to the charges appearing on its surface

Explanation:

Since field inside a conductor is always 0.

Hence field due to charge q and those appearing at the surface cancel each other
