A small laser emits light at power 5.00 mW and wavelength 633 nm. The laser beam is focused (narrowed) until its diameter matches the1266 nm diameter of a sphere placed in its path. The sphere is perfectly absorbing and has density 5.00e3 kg/m^3. What are?
1. The radiation pressure on the sphere
2. The magnitude of the corresponding force
3. The beam intensity at the sphere's location
4. The magnitude of the acceleration that force alone would give the sphere
