A conducting sphere of radius R is charged to a potential of V volts. Then the electric field at a distance `r ( gt R)` from the centre of the sphere would be

A

`(rho R)/(3epsilon_0)`

B

`(rho R)/(epsilon_0)`

C

`(rho R)/(3epsilon_0)`

D

`(3rho R)/(epsilon_0)`

Text Solution

Verified by Experts

The correct Answer is:
C
`E=1/(4piepsilon_0).(Qr)/(R^3) =(Qr)/((4/3piR^3)3epsilon_0)=(rhor)/(3epsilon_0)`
