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.

Indentical isolated conduction sphers 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters (Fig.a). The electrostatic force acting on spkhere 2 due to sphere 1 is F. Suppose now that a third identical sphere 3, having an insulation handle and initially neutral, is touched first to sphere 1 (Fig. b), then to sphere 2 (Fig. c), and dinally removed (Fig. d). The electrostatic force that now acts on sphere 2 has magnitude F'. What is the (F')/(F) ?

Two identical conducting spheres A and B, carry equal charge. They are separated by a distance much larger than their diameters, and the force between them is F. A third identical conducting spheres, C,is uncharged. Sphere C is first touched to A, then to B, and then removed. As a result, the force between A and B would be equal to :

Two equally charged metal spheres A and B repel each other with a force of 4xx 10^(-5)N . Another identical uncharged sphere C is touched to A and then placed at the mid-point of the line joining the sphere A and B. The net electric force on the sphere C is

Two indentical metallic spheres A and B, each carrying a charge q repel each other with a force F. A third metallic uncharged sphere C of the same size is made to touch the spheres A and B alternately and then removed away. What is the force of repulsion between A and B ?

Two charged identical metal spheres A and B repel each other with a force of 3 xx 10^(-8) N Another idenitcal uncharged sphere C is touhced with sphere A and then it is placed mid way between A and B. Then the magnitude of net force on C is
