Current Attempt in Progress Your answer is partially correct. In the figure, a laser beam of power 6.61 W and diameter 2.60 mm is directed upward at one circular face (of diameter d < 2.60 mm) of a perfectly reflecting cylinder. The cylinder is levitated because the upward radiation force matches the downward gravitational force. If the cylinder's density is 1.50 g/cm³, what is its height H? H.
