Code (Text): +q -a- -q | | a a | | +2q -a- -2q What are the horizontal and vertical components of the resultant electrostatic force on the charge in the lower left corner of the square if q = 0.9 10-7 C and a = 4.4 cm? (Assume the positive directions are upward and to the right.) For the horizontal component I got .0013081 N and for the Vertical I got 4.321 N, but neither one is correct. I found the charge between +2q and -2q, and then I added the charge from +2q to -q times cos(45). That should have given me the horizontal charge but it didn't. What am I doing wrong?
