Three metallic spheres A, B and C having radii are in ratio` 1 : 2 : 3`. Charge on sphere A is 6 `mu C` and sphere B and C are electrically neutral. If sphere A first contact with sphere B and then from C and ultimately contact from sphere B, then now charge on spheres A, B and C respectively will be-

Consider three identical metal spheres A, B and C . Sphere A carries charge + 6q , sphere B carries charge -3q and sphere C carries no charge . Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it . Finally the sphere C is touched to sphere B and separated from it . Find the final charge on the sphere C .

There are two identical spheres A and B. Now charge Q is established on each sphere. There is a third identical neutral sphere C. Now sphere C is first brought in contact with A and separated then brought in contact with B and separated. After this what will be charge on C ?

Consider three identical metal spheres A, B and C. Spheres A carres charge + 6q carries no charge . Spheres A and B are touchd together and them separated. Sphere C is then touched to sphere A and separated from it . Finally the sphere C is touched to sphere B and separated from it . Find the final chage on the sphere C .

Three concentric metallic spheres A, B and C of radii 1m, 2m and 3m respectively are charged to 0.56 nC, 2.12 nC and 5.0 nC. Calculate the potentials of the spheres.

Two homogeneous spheres A and B of masses m and 2 m having radii 2 a and a respectively are placed in contact. The ratio of distance of c.m from first sphere to the distance of c.m from second sphere is :

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?

Three concentric spherical metallic spheres A,B and C of radii a , b and c(a lt b lt c) have surface charge densities sigma , -sigma and sigma respectively.
