What is Electric Field Intensity?

Electric Field Intensity is defined as the force experienced by a unit positive test charge placed at a point in an electric field. Its dimensional formula is $MLT^{-3}A^{-1}$.

What is the formula for electric dipole moment and its SI unit?

The electric dipole moment $p$ for two equal and opposite charges $q$ separated by a distance $2L$ is given by $p = q \times (2L)$. Its SI unit is Coulomb-meter ($C \cdot m$).
