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 +3q.



Select True or False for the following statements.
The total charge on the inner surface of the small shell is -2q.
The total charge on the inner surface of the large shell is -5q.
The radial component of the electric field in the region c < r < d is given by +3q/(4pe0r2).
The electric field in the region r < a is zero.
The electric field in the region r > d is zero.
The total charge on the outer surface of the small shell is -5q.
The total charge on the outer surface of the large shell is +1q.

Explanation / Answer

The total charge on the inner surface of the large shell is +1q. T
The total charge on the inner surface of the small shell is -1q. F
The radial component of the electric field in the region r < a is given by -1q/(40r2). F
The radial component of the electric field in the region c < r < d is given by -1q/(40r2). F
The total charge on the outer surface of the small shell is zero. F
The total charge on the outer surface of the large shell is +2q. T
The radial component of the electric field in the region r > d is given by +2q/(40r2). T
