Question

in a conducting concentric shell if CHARGE Q IS GIVEN to outer shell does the charge induced in the inner shell too due to the outer Q charge???​

Answer 1

Answer:

If q' is the charge of inner sphere which is earthed, this inner sphere charge q' will induce a charge -q'

in inner surface of outer sphere and +q' on outer surface. Net charge on outer sphere is q.

Potential of inner sphere is due to its own charge q' and due to net charge on outer sphere.

Since potential of inner sphere is zero due to earthing, we have,
