Two small spheres, each carrying a charge q are placed r m apart and they interact with force F. If one of the sphere is taken around the other once in a circular path, the work done will be equal to

Two small spheres each carrying a charge q are placed r metre apart. If one of the spheres is taken around the other one in a circular path of radius r, the work done will be equal to

Two small spheres each carrying charge (+q) coulomb are kept r meter apart and are found to repel each other with a force of F newton. One of the sphere is moved around the other in a circular path of radius, r. The work done in Joules is

If we move an electron around the shell and around the solid sphere in a circular path, then what Is the work done for that motion?

(a) Two identical spheres having positive charges are placed 3 m apart repel each other with a force 8 xx 10^(-3) N . Now charges are connected by a metallic wire, they begin to repel each other with a force of 9 xx 10^(-3) N . Find initial charges on the spheres. (b) Two identical spheres having charges of opposite sign are placed 3 m apart attract other with a force 2.4 xx 10^(-3) N . Now spheres are touched and then placed at original separation repel with a force 10^(-3) N . Find initial charges on the spheres.
