A hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre:

A

zero as r increases for r < R, decreases as r increases for r > R

B

zero as r increases for r < R, increases as r increases for r > R

C

decreases as r increases for r < R and for r > R

D

increases as r increases for r < R and for r > R
