Negative charges A and B, 2.00 ? apart, exert forces of magnitude 3.00 ? on each other. If the charge in A is twice the charge in B, what is the value of the charge in A?

Expert Solution
Equation to find the Coulomb force between 2 charges.

Let the separation between charges and the force be in SI units.

F=k-qA-qBr2=k2qBqBr2=2kq2Br2qB=-F2kr
