### Electric Dipole and Derivation of Electric field intensity at different points of an electric dipole

Electric Dipole: An electric dipole is a system in which two equal magnitude and opposite point charged particles are placed at a very short distance apart. Electric Dipole Moment: The product of magnitude of one point charged particle and the distance between the charges is called the 'electric dipole moment'. It is vector quantity and the direction of electric dipole moment is along the axis of the dipole pointing from negative charge to positive charge. Electric Dipole Let us consider, the two charged particle, which has equal magnitude $+q$ coulomb and $-q$ coulomb is placed at a distance of $2l$ in a dipole so the electric dipole moment is → $\overrightarrow{p}=q\times \overrightarrow{2l}$ Unit: $C-m$ Or $Ampere-metre-sec$ Dimension: $[ALT]$ Electric field intensity due to an Electric Dipole: The electric field intensity due to an electric dipole can be measured at three different points: Electric
