The potential charge energy of 2 nC in an electric field is 6 μJ. What is the field potential at this point?

Up = 6 μJ = 6 * 10 ^ -6 J.
q = 2 nC = 2 * 10 ^ -9 C.
φ -?
The electrostatic potential φ is determined by the ratio of the potential energy Uп to the value of the charge q, which is located at this point. The potential energy of the charge is determined by the formula:
φ = Uп / q.
φ = 6 * 10 ^ -6 J / 2 * 10 ^ -9 C = 3 * 10 ^ 3 V.
Answer: Electrostatic potential φ = 3 * 10 ^ 3 V.
