Two spherical objects are separated by a distance of `1.80 xx 10^(-3) m`. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of `4.55 xx 10^(-21) N`. How many electrons did it take to produce the charge on one of the objects ?
