Answer

Explanation:

Step1: Recall Coulomb's law

Coulomb's law gives the electrical force between two point - charges. It states that the magnitude of the electrostatic force (F_e) between two point - charges (q_1) and (q_2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (d) between them. The proportionality constant is (k) (Coulomb's constant). The formula is (F_e = k\frac{q_1q_2}{d^2}).

Answer:

(F_e = k\frac{q_1q_2}{d^2}) (the third option)
