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.

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 +3q.

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

 The total charge on the inner surface of the small shell is -1q.

 The radial component of the electric field in the region c < r < d is given by -1q/(4nε0r2).

 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/(4nε0r2). 

 The radial component of the electric field in the region r < a is given by -1q/(4nε0r2).

 The total charge on the outer surface of the small shell is -4q.
