Consider the following figure. (The four charges are at the corners of a square. Take q = 1.08 µC and Q = 2.30 µC.)(a) In the figure, what are the magnitude and direction of the resultant force on q1? (Take q1 as the origin of the coordinate system and measure the angle counterclockwise from the positive x-axis, which is directed towards the right.)magnitude=?direction=? °(b) What is the resultant force on the center of mass of the four charges?
