A helium-neon laser of the type often found in physicslaboratories has a beam power of 7.00 mW at a wavelength of 633 nm.The beam is focused by a lens to a circular spot whose effectivediameter may be taken to be equal to 2.00 wavelengths.
Calculate the intensity of the focused beam.
Calculate the radiation pressure exerted on a tiny perfectlyabsorbing sphere whose diameter is that of the focal spot.
Calculate the force exerted on this sphere.
Calculate the magnitude of the acceleration impartedto it. Assume a sphere density of 4.50×103kg/m3.

A right triangular plate with height 4 ft and a base of 6 ft is submerged vertically in water so that the top is 2 ft below the surface. Express the hydrostatic force against one side of the plate as an integral and evaluate it.
Two particles of masses m1 and m2 are joined by a massless spring of natural length L and force constant k. Initially, m2 is resting on a table and I am holding m1 vertically above m2 at a height L. At time t=0, I project m1 vertically upward with in..
