Estimate the minimum kinetic energy an object of mass, m, would have if it were localized in space to within a certain radius from a reference point? Give a numerical estimate for each of the following cases: a) A1 gram mass of copper localized to a spherical region of radius of 10-3cm. b) The center of mass of the Earth (mass = 6 x 1024kg) localized to a spherical region of radius of 1 m. c) A proton (mass of about 1.7 x 10-27kg) localized to a spherical region of 1 atomic radius (x 10-8cm). d) An electron (mass of about 9 x 10-31kg) localized to a spherical region of 1 atomic radius (x 10-8cm). For all parts, express the answer in terms of Joules, but in addition, express the answers in electron volts for parts c and d. Note that h = 6.626 × 10-34Js and 1eV = 1.6 x 10-19J. Hints: Use the Heisenberg uncertainty principle. Make use of the fact that it involves standard deviations in
