The electrostatic potential phi_(r), of a spherical symmetrical system kept at origin, is shown in the adjacent figure, and given as phi_(r)=(q)/(4 pi epsilon_(0)r)(r ge R_(0)) phi_(r)=(q)/(4 piepsilon_(0)R_(0))(r le R_(0)) Which of the following option is incorrect ?

Answer»

For spherical region `r le R_(0)` total ELECTROSTATIC energy stored is zero
With in `r = 2R_(0)`, total CHARGE is `q//2`
There will be no charge anywhere except at r = R
Electric FIELD is discontinuous at `r = R_(0)`
