For spherical symmetrical charge distribution, variation of electric potential with distance from centre is given in diagram Given that : `V=(q)/(4pi epsilon_(0)R_(0))` for `r le R_(0) and V=(q)/(4 piepsilon_(0)r)` for `r ge R_(0)`
Then which option (s) are correct :
(1) Total charge within `2R_(0)` is q
(2) Total electrosstatic energy for `r le R_(0)` is non-zero
(3) At `r = R_(0)` electric field is discontinuous
(4) There will be no charge anywhere except at `r lt R_(0)`

Options

A. Total charge within `2R_(0)` is q
B. Total electrostatic energy for `r le R_(0)` is zero
C. At `r=R_(0)` electric field is discontinuous
D. There will be no charge anywhere except at `r=R_(0)`

Answer

A, B, C, D

Explanation

The given graph is of charged conducting sphere of radius `R_(0)`. The whole charge q distributs on the surface of the sphere.
