The charge density (charge per unit volume) of a spherical charge distribution is given by \(\rho(r)=\left\{\begin{array}{cl} \left(\frac{\rho_0}{a}\right) r & r \leq a \\ 0 & r>a \end{array}\right.\) The electric potential at the centre of the spherical distribution is
1
\(\frac{2 \rho_0 a^2}{3 \in_0}\)
2
\(\frac{3 \rho_0 a^2}{\epsilon_0}\)
3
\(\frac{\rho_0 a^2}{\epsilon_0}\)
4
\(\frac{\rho_0 a^2}{3 \epsilon_0}\)
