Three point charges are arranged as shown in the figure below. Find the magnitude and direction of the electric force on the particle q = 4.88 nC at the origin. (Let 12 = 0.325 m.) 13 magnitude Use Coulomb's law to find the force that each charge exerts on the charge at the origin and combine the forces to find the net force.
