In the image are three point charges, @1 = 21.4 AC, 02 = -30.6 MC, and Q3 = 67.3 AC, arranged according to - the figure. A fourth point charge is located at point A with a + A charge of QA = 17.5 MC. The charges form a square with height y of 80.1 cm and width x of 80.1 cm. - - - - - Calculate the magnitude F of the net force on the charge at point A. Q2 + 23 X F= N
