Define electric field intensity at a point.

Define electric field intensity due to point charger. Give is SI units.

Define electric field and electric field intensity at a point.

Determine the electric field intensity at a point on the perpendicular bisector of an electric dipole. If the dipole is very small, how will the field intensity be modified ?

Determine the electric field intensity at a point on the axis of an electric dipole. If the dipole is very small, how with the field intensity be modified ?

Define magneticfield intensity at a point. Derive an expression for magnetic field intensity at a point on the axial line of magnetic dipole with the help of diagram.
