Four point charges of equalmagnitude Q=55nC are placed on the corners of a rectangle of sidesD1=26cm and D2=11cm. The charges on the left side of the rectangleare positive while the charges of the right side of the rectangleare negative. Use a coordinate system fixed to the bottom left handcharge, with positive directions as shown in the figure

1)Calculate the vertical component of the net force, in newtons,on the charge which lies at the lower left corner of thetriangle.

2)Calculate the magnitude of the net force, in newtons, on thecharge located at the lower left corner of the rectangle.

3)Calculate the angle of the net force vector relative to the +xaxis, with the positive direction being counterclockwise from thepositive horizontal axis. Enter an angle between -180degrees and180degrees.
