A student is sitting 0.51 m directly below a lamp. The lamp is producing 640 nm light at a power of 75 W.

What is the force (in nN) exerted by the light of the lamp on the student if the cross-sectional area of the student is 0.14 m2? Assume that the lamp is a point source, that that the dielectric constant for the air is 1, and that the student perfectly reflects all the light.
