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