What is the nature of the symmetry of the field due to a point charge?

What is meant by the statement that the electric field of a point charge has spherical symmetry, whereas that f an electric dipole is cylindrically symmetrical?

Obtain expression for electric field due to a point charge

Graphically, represent the variation of electric field due to a point charge Q with magnitude of charge Q

Show that the electric field due to a point charge is conservative?

Graphically, represent the variation of electric field due to a point charge Q with 1//r^2 where r is the distance of the obervation point from the charge.
