Two neutral insulating small spheres are rubbed against each other and are then kept 4 m apart. If they attract
each other with a force of 3.6 N, then
calculate the charge on each sphere, and
calculate the number of electrons transferred from one sphere to the other during rubbing.

Answer:
F= 0.1 N = 9 * 109 * q2/r2
q2= 0.1 * 0.012/(9 * 109)
q2= 10/9 * 10-15
no of electrons transferred = q/1.6 * 10-19= 3.3333*10-16/1.6 * 10-19
=2.08 *103
