What is the equation for calculating the electrical force, cap f sub e , between two charges?

Coulomb’s law gives the electrical force as Fₑ = k(q₁q₂)/d², where k is Coulomb’s constant and d is the distance between the charges. The distance is squared and appears in the denominator, with k multiplying the fraction. Therefore, the correct choice is the equation with kq₁q₂ divided by d².
