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 -1q and the outer shell has a total charge of +4q. Select True or False for the following statements.

True False  The radial component of the electric field in the region c < r < d is given by +4q/(4??0r2).
True False  The total charge on the inner surface of the small shell is -5q.
True False  The total charge on the inner surface of the large shell is +1q.
True False  The total charge on the outer surface of the large shell is +3q.
True False  The radial component of the electric field in the region r > d is given by +4q/(4??0r2).
True False  The radial component of the electric field in the region r < a is given by +3q/(4??0r2).
True False  The total charge on the outer surface of the small shell is -5q.

a

Explanation / Answer

True False  The radial component of the electric field in the region c < r < d is given by +4q/(40r2).

False
True False  The total charge on the inner surface of the small shell is -5q.

False,it will be 2q
True False  The total charge on the inner surface of the large shell is +1q.

True
True False  The total charge on the outer surface of the large shell is +3q.

False
True False  The radial component of the electric field in the region r > d is given by +4q/(40r2).

False
True False  The radial component of the electric field in the region r < a is given by +3q/(40r2).

True
True False  The total charge on the outer surface of the small shell is -5q.

False
