A small laser emits light at a power of 5.00 mW. The laser beam is focussed until its diameter matches the 1266 nm diameter of a sphere placed in its path. The sphere is perfectly absorbing and has a density of 5.00 x103 kg/m3.a. Calculate the average energy per unit time per unit area (S).
b. Find the maximum values of E and B.
c. Calculate the radiation pressure on the sphere and the force exerted on the sphere.
d. Find the acceleration of the sphere.
