•26 In Fig. 33-38, a laser beam of power 4.60 W and diameter D = 2.60 mm is di- rected upward at one circular face (of diameter d< 2.60 mm) of a perfectly re- flecting cylinder. The cylinder is levitated because the upward radiation force H matches the downward gravitational force. If the cylinder's density is 1.20 g/cm', what is its height H?
