The nuclear charge (`Ze`) is non uniformlly distribute with in a nucleus of radius r. The charge density `rho(r)` (charge per unit volume) is dependent only on the radial distance r form the centre of the nucleus s shown in figure. The electric field is only along the radial direction. The electric field at `r=R` isA. independent of aB. directly proportional to aC. directly proportional to `a^(2)`D. inversely proportional to a |

Answer» Correct Answer - A `E=(1)/(4 pi in _(0))(Q)/(R^(2)),Q=` total charge `e=Ze` `rArrE=(Ze)/(4 pi inR^(2))` `rArr E` at `r=R` is independent of a |
