W F'our point charges of equal magnitude Q = 65 nC are placed on the corners of a rectangle of Sides 01 = 26 cm and 02 = 7 cm. The charges on the left side of the rectangle are positive while the charges on the right side of the rectangle are negative. Use a coordinate system where the positive y direction is up and the positive x direction is to the right. ' ' 1. Draw a free-body diagram for the charge on the lower left hand corner of the rectangle? 2. Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle. 3. Calculate the vertical component of the net force. in newtons, on the charge which lies at the lower left corner of the rectangle. 4. Calculate the magnitude of the net force. in newtons, on the charge located at the lower left corner of the rectangle. 5._ Calculate the angle of the net force vector relative to the +x axis, with the positive direction being counterclockwise from the positive horizontal axis. (l he angle should be between -180 and 180.)
