Laser light can be focused (at best) to a spot with radius r equal to its wavelength lambda. Suppose that a 1.0-W beam of green laser light (lambda=5*E-7m) is utilized to form such a spot and that a cylindrical particle of about that size (let the radius and height equal r) is illuminated with the laser. Estimate the acceleration of the particle, if its density equals that of water and it absorbs the radiation.
