A metallic sphere has a charge of `10 mu C`. A unit negative charge is brought from `A` to `B` both `100 cm` away from the sphere but `A` being east of it while `B` being on west. The net work done is

A metal sphere has a charge of -6.5 muC . When 5xx10^(13) electrons are removed from the sphere, what would be the net charge on it?

A metal sphere has a charge of -6 muC . When 5xx10^(12) electrons are removed from the sphere. What would be net charge on it ?

A metal sphere has a charge of -6 muC . When 5 xx 10 ^(12) electrons are removed from the sphere, what would be net charge on it?

A metal sphere of radius 1cm is charged with 3.14 mu C . Find the electric intensity at a distance 1 m from centre of metal sphere.

A metallic sphere A isolated from ground is charged to + 50 mu C . This sphere is brought in contact with other isolated metallics sphere B of half the radius of sphere A.The charge on the two sphere will be now in the ratio.

A metal sphere is suspended from a nylon thread. Initially, the metal sphere is uncharged. When a positively charged glass rod is brought close to the metal sphere, the sphere is drawn towards the rod. But if the sphere touches the rod, it suddenly flies away from the rod. Explain, why the sphere is first attracted then repelled?

A sphere of radius1 0 cm carries a charge of 1 mu C . Calculate the electric field at a distance of 30 cm from the center of the sphere

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-
