Coulomb Force


<div class="wp-block-create-block-problemblock">Two metal spheres are charged, q##_1## = 6Q and q##_2## = -2Q, and are separated by a distance d.  The attractive force between these two spheres is 20 N.  The metal spheres are then brought together so they are touching, and then separated again a distance d.  What is the new charge on the metal spheres and what is the new force between them?</div>
