Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 2.4 cm. Two of the particles have a negative charge: q1 = -6.5 nC and q2 = -13.0 nC. The remaining particle has a positive charge, q3 = 8.0 nC. What is the net electric force acting on particle 3 due to particle 1 and particle 2?
Find the net force acting on particle 3 due to the presence of the other two particles. Report your answer as a magnitude and a direction measured from the positive x axis.
