What is the value of a charge that has an electric potential of 325 V and an electric potential energy of 0.025 J?

Electric potential is electric potential energy per unit charge: V = U/q, so q = U/V. Substituting the values gives q = 0.025 J ÷ 325 V ≈ 7.7 × 10⁻⁵ C. Therefore, the charge is 7.7 × 10⁻⁵ C, choice B.
