A dipole is formed by separating a +200 nC and -200 nC charge a distance of 30 mm. Determine the magnitude of the electric field at a distance of 12 meters measured perpendicularly from the midpoint between the charges. Express your answer in N/C

Electric Dipole

An electric dipole is a pair of equal and opposite charges placed at a very small distance from one another. The strength of a dipole is given by a vector quantity called a dipole moment $\left(\overrightarrow{p}\right)$. Dipole moment is given by the product of one of the charges in the dipole and the distance separating them. The direction of the dipole moment is from the negative to the positive charge.

If $q$ is the magnitude of the charge in the dipole and the two charges are separated by a distance $2a$, then the dipole moment

$\overrightarrow{p}=q\times 2a \hat{p}$
