A small metal sphere carrying charge + Q is located at the centre of the spherical cavity in large and charge metal sphere as shown in figure. Use Gauss law to find electric field at the point P1 and P2....... In this question shouldn't the net electric field be zero as field inside a conductor is zero????
Answers
Answer:
The uniform charge −Q will be induced on inner surface of the shell and +Q will be induced on outer surface. This is follows from conservation of charge and no static charges resides in the interior of a metal in electrical equilibrium.
