# An electricity and magnetism problem by Soumyadip Bijuli

A point charge $$q$$ is placed at a distance of $$2r$$ from the centre $$O$$ of a conducting charged sphere of radius $$r$$. Due to the induced charges on the sphere, find the electric potential at a point $$P$$ on the surface of sphere

Take $$\dfrac{Kq}r = 18 \text{ Volts}$$.
