A thin spherical insulating shell of radius R carries a uniformly distributed charge such that the potential at its surface is V 0 . A hole with a small area 
is made on the shell without affecting the rest of the shell. Which one of the following statements is correct?
A
The magnitude of electric field at a point, located on a line passing through the hole and shell's center, on a distance 2R from the center of the spherical shell will be reduced by 
B
The magnitude of electric field at the center of the shell is reduced by 
C
The ratio of the potential at the center of the shell to that of the point at 
R from center towards the hole will be 
R from center towards the hole will be
D
The potential at the center of the shell is reduced by 2 
V 0
V 0
