Question

Two identical conducting spheres having unequal positive charge q1 and q2 separated by a distance r. If they are made to touch each other and then separated again to the same distance, the electrostatic force between the spheres in this case will be (neglect induction of charges)

Answer 1

hi buddy
here's your answer looking for

To calculate the force exerted by charges between them is given by coloumbs law.

That states, force between two charges are directly proportional to the product of these charges and inversely proportional to the square of the distance between them.

so,
$f = \frac{q1 \times q2}{ {r}^{2} }$


so, this equation will help you
