Three point charges are arranged as shown in the figure below. Find the magnitude and direction of the electric force on the particle q = 4.74 nC at the origin. (Let 12 13328.19159 magnitude direction 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. N counterclockwise from the +x axis y q 12 6.00 nC +- -x 0.100 m -3.00 nC i 0.260 m.)
