Four point charges of equal magnitude Q = 45 nC are placed on the corners of a rectangle of sides D1 = 16 cm and D2 = 9 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.

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.
a) Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle.
b) Calculate the vertical component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle.
c)Calculate the magnitude of the net force, in newtons, on the charge located at the lower left corner of the rectangle.
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°.
