Question

a conducting shell has a charge of + 10 added service a charge of minus 20 is given at the centre of the cell what is the net charge on the outer surface of the shell
(a) +10e
(b) -20e
(c) -10e
(d) zero​

Answer 1

The conducting charge of the outer surface will be -10e

Explanation:

• As the charge for the inner surface is given as - 20e
• And the charge of the conduction shell surface is +10 e
• To calculate the net charge on the surface,  we will add both charges
• -20 e + 10 e
• = -10e
• When the charge is present at the center then inner charge is equally distributed,
