Explanation:
(1). Formula to calculate the potential difference is as follows.
=
=
=
=
= 38.7 volts
Therefore, magnitude of the potential difference between the two spheres is 38.7 volts.
(2). Now, formula to calculate the energy stored in the capacitor is as follows.
E =
=
=
Thus, the electric-field energy stored in the capacitor is .
