Two small identical conducting spheres are placed with their centers 0.71 m apart. One is given a charge of 12*109 C, the other a charge of 17*109 C.
a) Discover the electrostatic force exerted on one sphere by the other. Magnitude N direction
b) The spheres are connected by a conducting wire. Discover the electrostatic force among the two after equilibrium is reached, where both spheres have the same charge. Magnitude N direction
