Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 3.1cm . Two of the particles have a negative charge: q1 = -8.8nC and q2 = -17.6nC . The remaining particle has a positive charge, q3 = 8.0nC . What is the net electric force acting on particle 3 due to particle 1 and particle 2?
