If the charge on two rubber balls, is 3.0 microcoulombs? Would you be able to hold these balls apart? What does this tell you about the likelihood of finding these size charges on ordinary objects?

Answer #1

Let the separation between these two charges be of the order of 1m

r = 1 m

Q = 3 X 10-6 C

Force between the two charges is given by

F = 0.081 N

the force is very small which means that we can hold these balls apart.

We can easily find such charges on ordinary objects and we may not feel their presence because the electrostatic forces between them are very small.
