In a uniformly charges sphere of total charge Q and radius R, the electric field E is plotted as a function of distance from the centre. The graph which would corresponding to the above will be :-

Options

A.
B.
C.
D.

Answer

D

Explanation

For uniformly charges sphere
`E=(Kqr)/R^(3)" "(r lt R)`
`E=(Kq)/R^(2)" "(r=R)`
`E=(Kq)/r^(2)" "(r gt R)`
