Three-point charges are arranged as shown in the figure below. Find the magnitude and direction of the electric force on the particle q = 5.20 nC at the origin. (Let r12 = 0.260 m.) find magnitude and direction counterclockwise from the +x axis

A charged particle A exerts a force of 2.40 ?N to the right on charged particle B when the particles are 12.4 mm apart. Particle B moves straight away from A to make the distance between them 16.2 mm. What vector force does particle B then exert on A? ?N to the left

The figure below shows three small, charged spheres, all lying along the horizontal axis. Sphere A, at left, has a 6.90 nC charge. Sphere B has a 1.40 nC charge and is 3.00 cm to the right of A. Sphere C has a  −2.80 nC  charge and is 2.00 cm to the right of B. Find the magnitude (in N) and direction of the net electric force on each of the spheres. Three charges lie along a horizontal line. A positive charge labeled qA is on the left. 3.00 cm to its right is a positive charge labeled qB. 2.00 cm to the right of qB is a negative charge labeled qC.
