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!
