Radiation is always perpendicular to the surface of the disk

Reference no: EM13654389

A uniform circular disk of mass 0.0240 kg and radius0.400 m hangs vertically on a fixed, frictionless horizontal hingeat a point on its circumference. A beam of electromagneticradiation with intensity 10.0 x 10⁶ W/m² isincident on the disk in a direction perpendicular to its surface. The disk is perfectly absorbing, and the resulting radiationpressure makes the disk rotate. Find the angle through which thedisk rotates as it reaches its new equilibrium position.

Note: assume the radiation is always perpendicular to the surface of the disk.
