A charge of 3.75 10-9 C is located 3.1 m from a charge of -3.10 10-9 C. Find the magnitude of the electrostatic force exerted by one charge on the other.

Question

a)increases
or
b)decreases
or
c)remains the same

Answer 1

You have not said if the separation of the charges is changing. The choices offered do not answer the question.

I believe you copied the problem's choices incorrectly.

In any case, use Coulomb's to determine the magnitude of the electrostatic force
