Question
In a uniformly charged sphere of total chargeQ and radius R, the electric field E is plottedas a function of distance from the centre. Thegraph which would correspond to the abovewill be :-
Options
A.

B.

C.

D.

Solution
For uniformly charged sphere
(r < R)
(r = R)
(r > R)
so
(r < R)
(r = R)
(r > R) so
