The electric field intensity on the surface of a charged solid sphere of radius ' $r$ ' and volume charge density' $\rho$ ' is given by
  1. zero
  2. $\frac{\rho r}{3 \varepsilon_0}$
  3. $\frac{1}{4 \pi \epsilon_0} \frac{\rho}{\mathrm{r}}$
  4. $\frac{5 \rho r}{6 \epsilon_0}$

Solution

The electric field intensity on the surface is given by But $q=\frac{4}{3} \pi r^3 \rho$ Putting this value of q in Eq. (1) and simplifying we get $E=\frac{\rho r}{3 \varepsilon_0}$
