Electric Potential Due to a Solid Sphere of Charge
A small spher...
Question
A small sphere of radius r1 and charge q1 is enclosed by a sphericalshell of radius r2 and charge q2. Show that if q1 is positive, chargewill necessarily flow from the sphere to the shell (when the two areconnected by a wire) no matter what the charge q2 on the shell is.

Solution
From Gauss’s law, it can be concluded that the electric field between a sphere and a shell is determined by the charge q1 on the small sphere.
Thus, the potential difference (V) between the small sphere and the spherical shell will be independent of charge q2. So the potential difference V will always be positive for the positive charge q1.
