The electrostatic potential inside a charged spherical ball is given by \(\phi=a r^{2}+b\) where r is the distance from the centre; a, b are constants. Then the charge density inside ball is
- \(-6 a E_{a}!\)
- \(-24 \pi a \epsilon_{a}!\)
- \(-6 \mathrm{aE} \mathrm{E}_{\mathrm{B}}\)
- \(-24 a \epsilon_{n}\)
Answer
(C) -6 aE E _ B
