Two small identical conducting spheres are placed with their centers 0.70 m apart. One is given a charge of 1.2 x 10^-8 C, the other a charge of -2.2 x 10^-8 C.
A) Find the electrostatic force exerted on one sphere by the other.
magnitude ________N.
B) The spheres are connected by a conducting wire. Find the electrostatic force between the two after equlibrium is reached, where both spheres have the same charge.
magnitude _______N.
