Shown in figure is a shell made of a conductor. It has inner radius a and outer radius b, and carries charge Q. At its centre is a dipole 
as shown. In this case:
A
Surface charge density on the inner surface is uniform and equal to
B
Electric field outside the shell is the same as that of a point charge at the center of the shell.
C
Surface charge density on the outer surface depends on 
.
.
D
Surface charge density on the inner surface of the shell is zero everywhere.
