Two spherical objects are separated by a distance of ­1.80×10­3 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 4.55×1021 N. How many electron did? It take to produce the chargeon one of the objects?

The electrostatic force is computed with the formula
F=kq1q2r2
Since both objects acquire the same charge, you can view it as
F=kq2r2
where you already know F(force) and r (distance between them.) "k" is a constant, 8.99×10
So in this case you can calculate the value of q, the charge on one object. Once you've figured out q, just divide it by the fundamental charge, 1.6×10
To calculate the number of electrons on the object. I came up with about 8 electrons.
