Uncertainty principle

(a) Show that the kinetic energy of a nonrelativistic particle can be written in terms of its momentum as KE = P2 (squared)/2m. (b) Use the results of (a) to find the minimum kinetic energy of a proton confined withinna nucleus haveing a diamter of 1.0 x 10-15 m.

Electrons and magnetic field

Photons of wavelength 450 nm are incident on a metal. The most energetic electrons ejected from the metal are bent into a circular arc of radius 20.0 cm by a magnetic field with a magnitude of 2 x 10-5 T. What is the work function of the metal?
