A non-conducting solid sphere of radius ...

A non-conducting solid sphere of radius R is uniformly charged. The magnitude of the electric filed due to the sphere at a distance r from its centre

A

increases as r increases, for rltR

B

decreases as r increases, for `0 ltrltoo`

C

decreases as r increases, for `Rltrltoo`

D

is discontinuous at `r = R`.

Text Solution

Verified by Experts

The expressions of the electrical field are
inside the sphere `(rltR),E=(1)/(4piepsi_(0))(Q)/(R^(3))r`
Outside the sphere `(R lt r lt infty),E=(1)/(4piepsi_(0))(Q)/(r^(2))`
Hence, E increases for `rltR` and decreases for `Eltrltinfty`.
