based on radiation force, photon theory of light
A cylindrical laser light beam of intensity I radius δ is used to levitate a solid aluminum sphere of radius R by focusing it in the sphere from below as shown. The laser light is reflected by the sphere without any absorption. Find force exerted by beam on sphere.
Now consider special case of δ≪R , find force exerted by beam and mass of sphere if power of beam is 1 kW Advanced problems Playlist
