Question

In the figure on the left, you can see each corner of a cube electron (-e) was placed. One side of the cube its length is 2 meters. A load of (+ 2e) size since it is placed in the very center of the cube, (a) What is the electrical potential energy of the system? (e = 1.6 x 10-19 C) (10 points) (b) This electrical potential energy is positive (+) or negative (-) to work-energy theorem according to how you explain. (10 points) (Note: k = 1 / 4πɛ = 9 x 109 Nm2 Take it as / C.)
