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)` A. Total charge within `2R_(0)` is qB. Total electrostatic energy for `r le R_(0)` is zeroC. At `r=R_(0)` electric field is discontinuousD. There will be no charge anywhere except at `r=R_(0)` |
