An isolated conducting spherical shell carries a negative charge. What will happe if a positively charged metal object is placed in contact with the shell interior? Assume that the positive charge is (a) less than (b) equal to (c ) greater than the negative charge in magnitude.

Answer»

SOLUTION :Net charge will come on the outer surface of the SPHERICAL shell
(a) if the positive charge is less than the NEGATIVE on the conducting spherical shell, the net charge will be negative.
(B) if the charge is equal to negative charge the net charge is zero.
(c ) if the charge is GREATER than the negative charge , net charge is positive
