What is the strength of the electric field at the position indicated by the dot in the figure, given that $q=0\mathrm{.}88nC$ and $$d=5\mathrm{.}01cm?$

What is the direction of the electric field at the position indicated by the dot in the figure? Specify the direction as an angle with respect to the horizontal; enter a positive angle if it is above the horizontal and a negative angle if it is below.
