Two electrical conducting balls a and b have charge q1 and q2 but q1 is not equal to q2 then the balls are brought together so that they touch each other and then kept at original distance then what will happen to the force?

The force will increases to is maximum value if charge are like or decreases if they are alike. Because after touch charge on each become half of addition of both charge before touch.Hope it clears. If u have doubts then please clearify. And if u like my answer then please approve answer
