Explain by graph how the electric field by thin spherical shell depends on the distance of point from centre.

The Electric field at a point is

In figure there is graph of electric field E_(r) at point against the distance of that point from centre of the body so....

Obtain the expression of electric field by thin spherical shell with uniform charge distribution at a point inside it.

Write equation of electric field by point charge How does it depend on distance ?

Obtain the expression of electric field by thir spherical shell with uniform charge distribution at a point outside it.

How does the electric field lines depend on area ?

Explain the energy of orbital and extent of shielding in same shell depends on shape of orbitals.

The gravitational force between a hollow spherical shell (of radius R and uniform density) and a point mass is E. Show the nature of F versus r graph where r is the distance of the point from the centre of the hollow spherical shell of uniform density.

Explain the electric field lines and the magnitude of electric field.
