Two small identical conducting spheres are placed with their centers 0.72 m apart. One is given a charge of 1.2 multiply.gif 10-8 C, the other a charge of -1.6*10-8 C.
a) Discover the electrostatic force exerted on one sphere by the other.
Magnitude _________N
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
