Two spherical objects are separated by a distance of 1.41 × 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 1.40 × 10^20 N. How many electrons did it take to produce the charge on one of the objects?
