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. The total charge on the inner surface of the small shell is -5q The electric field in the region r d is zero. E The total charge on the inner surface of the large she is +1q. D The total charge on the outer surface of the small shell is -5q The electric field in the region r a is zero. The electric field in the region c

Explanation / Answer

For a conducting body the total charge is only on the surface,and inside the conducting body ,the charge is zero

using gauss law integral (E*dA) = q_inside/eo = 0/eo = 0 i.e E = 0 N/C inside the shell

if there is no charge ,then electric field inside the conducting body is zero

The total charge on the inner surface of the samm shell is -5q is False

The electric field in the region r > d is zero False

The total charge on the inner surface of the large shell is +1q is true

the total charge on the outer surface of the small shell is -5 q is false

the electric field in the region r <a is zero is TRue

the electric field in teh region c < r < d is zero is true

the total charge on the outer surface of the large shell is +3q is false
