Question

A thick spherical conducting shell with an inner radius of 0.200 m and an outer radius of 0.250 m has a very small charged sphere suspended in its center. The sphere has a charge of 36.1 mC, and the conducting shell has a net charge of 36.1 mC. What is the net amount of charge that resides on the following?

(a) the inner surface of the shell

________mC

(b) the outer surface of the shell

________mC

What is the charge density on the following?

(c) the inner surface of the shell

__________C/m2

(d) the outer surface of the shell

_________C/m2

Explanation / Answer

a)36.1 mC......in order to make electric field in conductor zero, inner surface charge will be negative of that at center

b) 0 mC.....because whole charge of conduction shell is on innersurface

c)0.0361 /(4x pi x 0.2 x 0.2) = -0.0718 C/m2

d) 0 C/m2 because there is zero charge
