A neutral spherical conductor has a cavity. A point charge q is located inside it. It is in equilibrium. An external electric field (E) is switched on that is directed parallel to the line joining the centre of the sphere to the point charge. (a) What is the direction of acceleration of the charge particle inside the cavity after E is switched on. (b) How is the induced charge on the wall of the cavity affected due to the external field.

Text Solution

Verified by Experts

The correct Answer is:
(a). No acceleration
(b). Not affected.
