I used the equation

E= ((k)(q))/r^2

for each q1 and q2.

I don't know what to do next to find the mag. at x = 0.5 and y = 0.5.

thanks in advance

then it's a matter of summing both electric fields.(Vector algebra).

to find magnitude: think Pythagorean ;)

when you say use 0.5, 0.5... does that mean that r = 0.5?

so it would be 0.5^2 for the denominator?

so it would be 0.5^2 for the denominator?

There is a distance of 1.0 m between q1 and q2.

The points (0.5, 0.5) would be in between q1 and q2?

So the distance would be 0.5m and thus r = 0.5?
