JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

Electric field intensity due to a nonconducting charged solid sphere at a point outside the sphere is $\frac{\mathrm{R}^3 \rho}{3 \epsilon_0 \mathrm{r}^2}$

Electric field intensity at a point on its surface due to an insulating charged solid sphere will be $\frac{R \rho}{3 \epsilon_0}$

Electric field intensity due to an insulating charged solid sphere at a point located inside the surface at a distance ' $r$ ' from the centre of the sphere, will be $\frac{\rho r}{3 \epsilon_0}$

Electric field intensity due to a solid insulating charged sphere, at points inside the sphere
will be zero
