A metal sphere is held fixed on a smooth horizontal insulated plane and another metal sphere is placed some distacne away. If the fixed sphere is given a charge how will the other sphere react ?

An isolated solid metallic sphere is given +Q charge. The charge will be distributed on the sphere

A hollow metallic sphere is charged. Insider the sphere

How can you charge a metal sphere positively?

An siolated metal sphere of radius 'r' is given a charge 'q' . The potential energy of the sphere is

Three metal spheres A,B and C are mounted on insulating stands. The spheres are touching one another, as shown in the diagram A strong positively charged object it brought near sphere A and a strong negative charge is brought near sphere C. While the charged objects remains near spheres A anc C, sphere B is removed by means of its insulating stand. After the charged objects are removed, sphere B is first touched to sphere A and then to sphere C. The resulting charge on B would be-
