A positive charge (+e) is located at a position (0,-d/2, 0) and a negative charge (-e) is located at another position (+d/2, 0, 0) in space respectively. Assume an isolated positive test charge (+1 C) is placed at the origin O(0,0). (a) Sketch the charge distribution of the network in graph up-to the scale. (b) Determine the magnitude and direction of the net Coulomb force exerted on the test charge at the origin by the network of opposite charges (+e, -e) separated at 5.0 cm. (c) Determine the magnitude and direction of the total Electric Field Intensity (E) experienced by the test charge at the origin due to the opposite charges (+e, -e) placed at 5.0 cm apart.
