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. For spherical region `rleR_0`. Total electrostatic energy stored is zero.B. Within `r = 2R_0`, total charge is Q.C. There will be no charge anywhere except at ` r = R_0` .D. Electric field is discontinuous at `r = R_0` . |

Answer» For `rgtR_(0),E=(dphi)/(dr)=(Q)/(4piepsi_(0)r^(2))` therefore, charge enclosed by concentric spherical surface at r is `2R_(0)=epsi_(0)phi_(E)4pir^(2)=epsi_(0)(Q)/(4piepsi_(0)r^(2))=Q` For `rltR_(0),E=-(dV)/(dr)=0` and for `rgtR_(0)E=-(dV)/(dr)=4piepsi_(0)r^(2)` (here `V=phi`) |
