I got this problem wrong in my text's student companion website, but I don't understand why. Could someone let me know what went wrong?
What are the horizontal and the vertical components of the resultant electrostatic force on the charge in the lower left corner of the square if q = 0.10 micro Coulombs (Or uC as I cannot remember how to type the Greek letter equivalent.) and a = 5.0cm?
Fh = F-q + F-2q(cos(45))
Fv = -F+q + F-q(sin(45))
I get .17E-6 N for Fh and -2.1E-7 N for Fv. I think I may have mixed up some decimal places on Fh, but the solution presented is .17 N for Fh and -0.046 for Fv. I just don't understand what I did wrong though.
