the figure shows a charge `q` placed inside a cavity in an uncharged conductor, Now if na external electric field is switched on

Options

A. Only induced charge on outer surface will redistribute
B. Only induced charge on inner surface will redistribute
C. both induced charge on outer and inner surface will redistribute
D. force on charge `q` placed inside the cavity will change.

Answer

A

Explanation

The figure shows a charge `q` placed inside a cavity in an unchanged conductor,Now if an external electric field is switched on : (A) Only induced charge on outer surface will redistribute.
Only induced charge on inner surface will redistribute
(C ) both induced charge on outer and inner surface will redistribute
(D) force on charge `q` placed inside the cavity will charge.
