A polarized light beam, with a 6.41 millimeter diameter circular cross section, is perpendicularly incident on an ideal polarizer, serving here as an analyzer. The intensity of the light is 3.57 kW/m2 and the angle between the beam's polarization direction and the polarization axis of the polarizer is 19.1 degree. Obtain what force does the light exert on polarizer?
Answer in piconewtons.
