Discuss that potential is spherically symmetric for a point charge. Define eV, MeV and meV.

Find the potential at a point due to two point charges. Discuss the result for a general charge distribution?

The potential at a certain distance from a point charge is 600 volt and the electric field is 200 NC^-1 find the magnitude of the charge.

The potential at a certain distance from a point charge is 600 volt and the electric field is 200 NC^-1 find the distance of the point from the 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?
