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 centre of sphere and the other end to a rigid wall as shown in figure. Sphere is in equilibrium. Spring constant of spring is K. Then compression in spring is –
(Radius of sphere is R)
(Neglect any thermal effect and friction is absent)
