At a certain distance from a point charge the electric field is `500 V m^(-1)` and the potential is 3000 V. The distance is

A

6 m

B

12 m

C

36 m

D

144 m

Text Solution

Verified by Experts

The correct Answer is:
A
`E = q/(4pi epsi_0 r^2) = 500 Vm^(-1) and V = q/(4pi epsi_0 r) = 3000 V rArr r = V/E = 3000/500 = 6 m`
