An uncharged metal sphere is placed between two equal and oppositely charged metal plates. The nature of line of force will be

There is force of repulsion between two like charges, because electric lines of force

Two identical spheres of radii 10 cm each are placed in between two rigid walls (vertical) as shown. The spacing between the walls is 36 cm. Then find the force of contact between the spheres, if the weight of each sphere is 'W'.

A metallic slab is introduced between the two charged parallel plates as shown below. Sketch the electric lines of force between the plates.

A small uncharged sphere is placed in contact with an equal and similar charged sphere and then removed to a distance of 4 cm. The force of repulsion between them is now 9xx10^(-5) N. What was the original charges in the charged sphere?

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

An uncharged metallic solid sphere of radius R is placed at a distance 2R from point charge Q as shown in figure. The electric field intensity due to induced charge at centre of sphere is
