Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 3.7cm . Two of the particles have a negative charge: = -7.9 nC and = -15.8 nC. The remaining particle has a positive charge, = 8.0 nC. What is the net electric force acting on particle 3 due to particle 1 and particle 2? 1) Find the net force acting on particle 3 due to the presence of the other two particles. Report you answer as a magnitude and a direction measured from the positive x axis.
A charge of -3.0 nC is at the origin and a second charge of 13.0 nC is at x = 8.00 m. Find the magnitude and direction of the electric field halfway in between the two charges.
