A metal sphere of radius R carrying q (+ve) charges is shown in the figure.
br "A sphere of radius 1cm can hold a charge of 1 coulomb" Comment on the statement.

A metal sphere of radius R carrying q (+ve) charges is shown in the figure. br Draw the electric lines of force related to this metal sphere.

A metal sphere of radius R carrying q (+ve) charges is shown in the figure. br Derive the strength of electric field at a distance r from the centre of sphere.

A metallic sphere of radius '4 cm' is melted and recast. How many small spheres of radius '1 cm' will get from it?

Equipotentiai surface is a surface on which the electric potential is the same at every point:- A point charge +q Is placed at the centre of a sphere of radius B. An other point charge +q is take from a point A to another diametrically opposite point B on the surface of the sphere. Calculate the work done for this.
