A uniform beam of light of intensity $$60\ \text{mW m}^{-2}$$ is incident on a totally absorbing sphere of radius $$2.0\ \mu\text{m}$$. The density of the material of the sphere is $$\rho=5.0\times10^3\ \text{kg m}^{-3}$$. The sphere is placed in a region of space where gravitational force can be neglected or ignored. The magnitude of acceleration of the sphere due to the incidence of the light is
