A polarized light beam, with a 7.33-mm-diameter circular cross section, is perpendicularly incident on an ideal polarizer, serving here as an analyzer. The intensity of the light is 3.71 kW/m2 and the angle between the beam\'s polarization direction and the polarization axis of the polarizer is 18.3°. What force in piconewtons does the light exert on the polarizer?
A cord is wrapped around the rim of a solid uniform wheel 0.300 in radius and of mass 7.80 . A steady horizontal pull of 40.0 to the right is exerted on cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearing..
