Two point dipoles $p \hat{k}$ and $\frac{p}{2} \hat{k}$ are located at $(0, 0, 0)$ and $(1 m, 0, 2 m)$ respectively. The resultant electric field due to the two dipoles at the point $(1 m, 0, 0)$ is

Options:

Answer:

Solution:

The given point is on axis of $\frac{p}{2}$ dipole and at equatorial line of $p$ dipole so that field at given point is $(E_{1} + E_{2})$
$E_{1} = \frac{2 K ( p /2 )}{2 ^{3}} = \frac{K p}{8} (+ \hat{k}) E_{2} = \frac{K p}{1} (- \hat{k}) E_{1} + E_{2} = - \frac{7}{8} K p (- \hat{k}) = - \frac{7 p}{32 π ϵ _{0}} \hat{k} 250 \times 9.8$
