A 7.2 * 10-5 C charge has an electric potential energy of 1.08 * 10-2 J. The electric potential, to the nearest whole number, is V.

The electric potential (also called voltage) is the potential energy per unit of charge:

V = U/q

(Remember the formula is different for a capacitor - This formula only applies to charged particles, not dipole systems)

So this is about how an amount of energy is "distributed" among several charged particles.

V = (1.08 * 10-2 J) / (7.2 * 10-5 C) = 150J/C=150V
