A solid sphere of radius `R` is charged uniformly. The electrostatic potential `V` is plotted as a function of distance `r` from the centre of th sphere. Which of the following best represents the resulting curve?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
`V=(kQ)/(2R^3) (3R^2-r^2). R lt r , =(kQ)/r, r gt R (K=1/(4 pi e_0))`
