well, I'm solving one question from 12U physics, and my answer don't match with others.
the question is at attached file. I do not know how to put it in here
Fex = 1.35, Fey = 1.35, and Fnet = 1.91 (45°)
this one make sense, however on next one, which is
"What is the net electric field acting on charge 1"
I think using equation, Fe = qε, and q is 3 x 10-5,
both εx and εy should be 1.35/(3 x 10-5)
however the answer that I've match with this says
Fex = εx and the marker says it is correct.
how does people think I should solve this?
Fe = kq1q2/r2 = qε
