Question
Define electric field intensity. Write its SI unit. Write the magnitude and direction of electric field intensity due to an electric dipole of length 2a at the mid-point of the line joining the two charges.
Solution
The force experienced by a unit positive charge placed at that point is termed as the electric field intensity.
The SI unit of electric field intensity = NC–1.
Electric field at any equatorial point of a dipole is given by,
At the mid-point of the dipole, r = 0.
Hence,
The direction of E is from positive charge to negative charge.
