where r is the distance between their centres?
Two identical metallic blocks resting on a frictionless horizontal surface are connected by a light metallic spring having a spring constant k and an unstretched length l n as shown in the figure . a total charges of q is slowely placed on the system , causing the soring to streached to an equilibrium length l as shown in figure. determine the value of Q, assuming that all the charges reside on the block and that block are like point charges.

Two identical conducting spheres 1 and 2 carry equal amounts of charge and are ficed apart at a certain distance larger than their diameters. The spheres repel each other with an electrical force of 88mN. A thired identical sphere 3, having an insulating handle and initially uncharged, is touched first to sphere 1 and then to sphere 2 and finally removed. Find the force between spheres 1 and 2 as shown if Figure.
