Part a - Calculate the vertical component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle.

Part b - Calculate the magnitude of the net force, in newtons, on the charge located at the lower left corner of the rectangle.

Part c - 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°

Thanks in advance

(20\%) Problem 4: Four point charges of equal magnitude $$Q=55\mathrm{nC}$$ are placed on the corners of a rectangle of sides $$D_1=29\mathrm{cm}$$ and $$D_2=12\mathrm{cm}$$. 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.
