## Homework Statement

In the figure (attached), find the magnitude and direction of the electric field at points A, B, C and D.

## Homework Equations

E = kQ / r^2

## The Attempt at a Solution

I'm just a little lost with the directions/if I need to be including angles

so for point A:

E = k 7.5e^5C / 0.25m + k 7.5e^5C / ?

is it 0.55m (as figured out by Pythagorean theorem) or would it be the X is 0.55cos26 and Y is 0.55 sin26 + the other charge (since it is only in the Y direction)

thanks!!
