A non-conducting solid sphere of radius R is uniformly charged. The magnitude of the electric filed due to the sphere at a distance r from its centreA. increases as `r` increases for `r lt R`B. decreases as `r` increases for `0 lt r lt oo`C. decreases as `r` increases for `R lt r lt oo`D. is discontiues at `r = R` |

Answer» Correct Answer - A::C for `r lt R, E = (kQ)/(R^(3)) r, i.e., E prop r` for `r gt R, i.e., R lt r lt oo, E = (kQ)/(r^(2)), i.e., E prop (1)/(r^(2))` |
