Two equally charged, Identical metal spheres A and B repel each other with a force `P` The spheres are kept fixed with a distance 7 between them. A third identical, but uncharged sphere is brought in contact with A and then placed at the mid point of the line Joining A and B. The magnitude of the net electric force on is:

Two equally charged, indentical metal spheres A and B repel each other with a force F" . The spheres are kept fixed with a distance r between them. A third identical, but uncharged sphere C is brought in contact with A and The magnitude of the net electric force on C is

Two similarly and equally charged identical metal spheres A and B repel each other with a force of 2xx10^(-5)N . A third identical unchared sphere C is touched with A and then placed at the midpoint between A and B. Find the net electric force on C.

There are two small identical metallic spheres A and B each carrying same charge. These two spheres are found to repel each other with a force P. A third identical neutral metal sphere C is first brought in contact with A and then B. The sphere C is taken away from A and B. The magnitude of electric force now is found to be 3F/x. What is x?

Two equally charged identical metal spheres X and Y repel each other with a force 5* 10^-4* N another identical uncharged sphere C is touched to A and then placed at the mid-point between X and Y. Net electric force on C is

There are two charged identical metal spheres A and B repel each other with a force 3xx10^(-5)N . Another identical uncharged sphere C is touched with A and then placed at the mid-point between A and B. Net force on 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 ?
