Two charges, $+$q and $-$q$,$ are located in the x$-$y plane at points $(0,+$d$/2)$ and $(0,-$d$/2),$ respectively. Calculate the magnitude of the electric field at point P with the superposition principle. Data: q $=31\mathrm{.}0$ nC$,$ d $=4\mathrm{.}60$ mm and P is at x $=92\mathrm{.}0$ mm$.$Two charges, $+q$ and $-q,$ are located in the $x-y$ plane at points $(0,+\frac{d}{2})$ and $(0,-\frac{d}{2}),$ respectively. Calculate the magnitude of the

electric field at point $P$ with the superposition principle.

Data: $a=31\mathrm{.}0n{C}_{j,}d=4\mathrm{.}60mm$ and $P$ is at $x=92\mathrm{.}0mm.$

By the principle of linear superposition, the total electric field at position $P$ is the vector sum of the electric field contribution from

charges $+Q$ and $-Q.$

In the previous problem, you can get an approximate answer for the electric field at point $P$ by using the electric dipole

approximation which is valid for the limit $x>>d.$ Calculate the magnitude of the electric field at point $P$ with this approximation and

the same values for $Q,d$ and $x$ as in the previous problem.
