Someone plans to float a small, totally absorbing sphere 0.500 m above an isotropic point source of light, so that the upward radiation force from the light matches the downward gravitational force on the sphere. the sphere’s density is 19.0 g/cm3, and its radius is 2.00 mm. (a) what power would be required of the light source?
