Question

Define electric field intensity. Write its s. L unit. Write the magnitude and direction of electric field intensity due to an electric dipole of length 2a at the mid- point of the tine joining the two charges

Answer 1

Electric intensity is the strength of electric field at a point. Electric intensity at a point is defined as the force experienced. per unit positive charge at a point placed in the electric field. or. It may also be also defined as the electrostatic force per unit.

Answer 2

Electric Field Intensity :

The electric field intensity of any point is defined as the force experienced by unit positive charge placed at that point.

$\large\tt\red{E=\frac{F}{q_0}}$

The SI unit of electric field intensity

$\large \tt\orange{NC^{-1}}$

Electric field at any equatorial point of a dipole

$\large \tt{}is \: \: \: \green {\vec{E}=\frac{1}{4\pi\:\varepsilon_0}\frac{\vec{p}}{(r^2+a^2)^\frac{3}{2}}}$

At the mid-point of the dipole, r=0 so ,

$\large \tt \purple{\vec{E}=\frac{1}{4\pi\:\varepsilon_0}\frac{\vec{p}}{a^3}}$
