Four point charges of equal magnitude Q = 75 nC are placed on the corners of a rectangle of sides D1 = 29 cm and D2 = 5 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. Part a Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle. Part b Calculate the vertical component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle. Part c Calculate the magnitude of the net force, in newtons, on the charge located at the lower left corner of the rectangle. Part d Calculate the angle of the net force vector relative to the +x axis, with the positive direction being counterclockwise from the positive horizontal axis. Enter an angle between -180° and 180°.
