$2)$ Four charged particles $($two having a charge $\backslash (+$Q $\backslash )$ and two having a charge $\backslash (-$Q $\backslash ))$ are distributed as shown in the following figure. Each charge is equidistant from the origin. Determine the direction of the net electric field at point $\backslash ($ P $\backslash ).$

A$)$ directly left $($negative $\backslash ($ x $\backslash )$ direction$)$

B$)$ upwards, towards the right

C$)$ directly up $($in the positive $\backslash ($ y $\backslash )$ direction$)$

D$)$ the net field is zero, so there is no direction

E$)$ upwards, towards the left
