The potential energy stored in a capacitor is given by:

where
C is the capacitance of the capacitor
V is the potential difference across the plates of the capacitor
In our problem,


Therefore, the potential energy of the capacitor is
Answer:
C
Explanation:
Because everything on Earth falls at the same speed, the masses of the balls do not matter. Since the acceleration due to gravity is constant, their speeds will both be increasing at the same rate, and therefore the difference in speeds would remain constant until they hit the ground. Hope this helps!
