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

Options

A. decreases as r increases for `rltR` and `rgtR`
B. increases as r increases for `rltR` and `rgtR`
C. zero as r increases for `rltR`, decreases as r increases for `rgtR`
D. zero as r increases for `rltR`, increases for `rgtR`

Answer

C

Explanation

For hollow conducting sphere
For `rltR,E=0`
For `rgtRrArrE=(Keq)/(r^(2))` so e decreases
