If q1 and q2 have the same charge of 60 µC with a magnitude of the force between them is 500 N, what is the distance separated these two charges?

Answer 1

Use Coulomb's Law to solve for d: F_e = k_eQ₁Q₂/d²

Solve for d and let Q₁=Q₂ = Q d = sqrt(k_eQ²/F_e)

k_e = 8.99 x 10⁹ and 60μC = 6 x 10^-5 Coulombs.
