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.
True False  The radial component of the electric field in the region r > d is given by +1q/(4??0r2).
True False  The total charge on the inner surface of the large shell is +2q.
True False  The electric field in the region c < r < d is zero.
True False  The total charge on the outer surface of the small shell is -5q.
True False  The total charge on the inner surface of the small shell is zero.
True False  The radial component of the electric field in the region r < a is given by +1q/(4??0r2).
True False  The total charge on the outer surface of the large shell is +1q.

Explanation / Answer

True The radial component of the electric field in the region r > d is given by +1q/(4??0r2).
True The total charge on the inner surface of the large shell is +2q.
False  The electric field in the region c < r < d is zero.
False  The total charge on the outer surface of the small shell is -5q.
True The total charge on the inner surface of the small shell is zero.
True The radial component of the electric field in the region r < a is given by +1q/(4??0r2).
False  The total charge on the outer surface of the large shell is +1q.
