im having trouble finding the(adsbygoogle = window.adsbygoogle || []).push({}); electric potential at a point inside a sphereat r= 40 cm where the radius of the sphere is 50 cm and the charge Q is 12 micro C.

i know that v= kQ/r at a point on the surface and at a point outside the sphere but what to i do now that i cant use total charge

does any have an idea?

please help its driving me mad
