Question

A small conducting spherical shell with inner radius a and outer radius b is concentric with a larger conducting spherical shell with inner radius c and outer radius d. The inner shell has a total charge of -2q and the outer shell has a total charge of +4q. Select True or False for the following statements.

The total charge on the inner surface of the large shell is zero.

The total charge on the outer surface of the small shell is zero.

The total charge on the outer surface of the large shell is +2q.

The radial component of the electric field in the region r d is given by +2q/(40r2).

Use Gauss's Law.

Explanation / Answer

for a conducting spherical shell the charge resides only on th e surface so

True The total charge on the inner surface of the large shell is zero

False    The total charge on the outer surface of the small shell is zero

False The total charge on the outer surface of the large shell is +2q. ( the answer is +4q)
