Q. A perfectly reflecting body (sphere in shape) is placed on a path of parallel light beam of intensity I shown in figure. One end of a spring is attached to the centre of the sphere and the other end to a rigid wall as shown in the figure. Sphere is in equilibrium. Spring constant of spring is K. Then compression in spring is
(Radius of sphere is R, c is the velocity of light and neglect any thermal effect and friction )
