A square plate of side length L absorbs all radiation incident on it. A point source of light is placed at a point P which is directly above a corner of the plate at a height L. The incident light on the plate produces a force of magnitude `F_(0)` on the plate. Calculate the magnitude of force on the plate if the source is moved to a point Q (Q is midpoint of the line PR).
