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 +4q.
Select True or False for the following statements.
______The radial component of the electric field in the region r < a is given by +2q/(4??0r2).
______The radial component of the electric field in the region c < r < d is given by -2q/(4??0r2).
______The total charge on the outer surface of the large shell is +2q.
______The total charge on the inner surface of the large shell is -6q.
______The total charge on the inner surface of the small shell is -2q.
______The radial component of the electric field in the region r > d is given by +2q/(4??0r2).
______The total charge on the outer surface of the small shell is zero.
