You are performing research on the development of optomechanical systems. In one of your experiments, a uniform circular disk of mass m = 24.8 g and radius r = 39.0 cm hangs vertically from a fixed, frictionless, horizontal hinge at a point on its circumference as shown below. Front view You aim a beam of electromagnetic radiation with intensity 9.5 MW/m so that it is incident on the disk in a direction perpendicular to its surface. The intensity of the radiation is uniform over the entire face of the disk. The disk is perfectly absorbing, and the resulting radiation pressure makes the disk rotate about the hinge, as shown below. m Side view In order for the rotation of the disk to activate a switch in a circuit, the disk must rotate through 3.00. Determine the angle (in degrees) through which the disk rotates. 4.41
