A spherical symmetric charge system is centered at origin. Given, Electric potential
`V=(Q)/(4piepsilon_0R_0)(rleR_0)`, `V=(Q)/(4piepsilon_0r)(rgtR_0)`

A

(a) Within `r=2R_0` total enclosed net charge is Q

B

(b) Electric field is discontinued at `r=R_0`

C

(c) Charge is only present at `r=R_0`

D

(d) Electrostatic energy is zero for `rltR_0`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
(a) The whole charge Q will be enclosed in a sphere of diameter `2R_0`. (b) Electric field E=zero inside the sphere. Hence electric field is discontinued at `r=R_0`.
(c) Changes in V and E are continuously present for `rgtR_0`. Option (c) is incorrect.
(d) For `rltR_0`, the potential V is constant and the electric intensity is zero. Obviously, the electrostatic energy is zero for `rltR_0`.
