Which one of the graphs represents the variation of electric field strength \[E\] with distance \[r\]from the centre of a uniformly charged conducting sphere ?

A)

B)

C)

D)

Correct Answer: A

Solution :

                 Electric field inside a spherical charge is zero everywhere, outside the shell the electric field E decreases rapidly \[\left( E\propto \frac{1}{{{r}^{2}}} \right)\] . Hence correct variation is
