Three point charges at q1 x = 0, q2 at x = 5 cm, and q3 at x = 3 cm. Find the ratio of q1:q2 if q3 is at equilibrium

Hey hope you get the answer but i suck at math sorry : (

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
