A 75 mW laser produces a (polarized) beam of 595 nm light. This light reflects normally off an object that reflects 90 percent of the incident energy. How long does it take this laser to give the surface a momentum of 0.005 kgm/s If the rms electric field inside the beam is 1600 v/m, what is the radius of the beam?
