1. The problem statement, all variables and given/known data li have three charges, 2 with same charge (magnitude and sign) and 1 with a smaller charge(smaller magnitude and opposite sign to the other two). how would i position them on a line so that the net force on any of them is zero 2. Relevant equations electric force, F = k(q1)(q2)/r^2 where q1 and q2 are point charges, k = 9*10^9, r is distance between charges electric force, point charge Fp = kq/r^2 3. The attempt at a solution where magnitude q_a > magnitude q_b fnet = k(+q_a)/a^2 + k(+q_a)/b + k(-q_b)/c^2 0 = k(+q_a)/a^2 + k(+q_a)/b + k(-q_b)/c^2 k(q_b)/c^2 = k(+q_a)/a^2 + k(+q_a)/b now what do i do? is my relationship correct?
