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 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.

Two metal plates A and B are connected to cell of emf 2V is shown in the figure br Redraw the diagram and draw lines of forces to represent electric field.

A hollowing metallic sphere of radius 10cm is charged such that potential on its surface is 80V. the potential at the center of the sphere would be.

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.

A hollow metal sphere of radius 5 cm is charged such that the potential on its surface to 10V. The potential at the centre of the sphere is ......(a)zero (b)10V (c)the same as that at a point 5 cm away from the surface (d)the same so that at a point 25 cm away from the surface

A metal sphere of radius 12 centimetres is melted and recast into '27 .' small spheres of equal size. What is the radius of each small sphere?
