Question 12

An isolated metal sphere of volume V0 V_0\,V0​ is given a charge QQQ, resulting in an electric potential V1 V_1\,V1​ at its surface. The sphere is then melted down and recast into a single solid sphere of volume 8V08V_08V0​. Assuming the charge Q Q\,Q remains unchanged, what is the new electric potential at the surface of the sphere?

A
