I am not sure but does this have anything to do with Coulomb's Law??
We know that Electric charges exert force on each other. The nature of force depends on the charge. Same charges repells while opposite charges attract. The nature of force is given by the inverse square law (coulomb's law)
<br>F = K*q1*q2/R^2 where R is the separation between the charges q1 and q2, K is a constant of ...
