totally reflecting disk has radius 8.00 mm and average density 600 kg>m3. A laser has an average power output Pav spread uniformly over a cylindrical beam of radius 2.00 mm. When the laser beam shines upward on the disk in a direction perpendicular to its flat surface, the radiation pressure produces a force equal to the weight of the disk. (a) What value of Pav is required
