A non-conducting sphere of radius \( R=5 \mathrm{~cm} \) has its centre at origin \( O \) of co-ordinate system, shown in figure-1.453. It has
\( \mathrm{P} \) a spherical cavity of radius \( r=1 \mathrm{~cm} \), whose centre is at \( (0,3 \mathrm{~cm}) \).
W Solid material of sphere has uniform positive charge density \( \rho=\frac{10^{-6}}{\pi} \mathrm{C} / \mathrm{m}^{3} \). Calculate potential at point \( P(4 \mathrm{~cm}, 0) \) :
