Question

(i) (ii) a. (iii) State Einstein's principal of equivalence. How does this relate to bending of light by stars? A negatively charged pion with kinetic energy of 800 MeV strikes a stationary proton. By considering conservation principles, show that the reaction t +p → 1° + Kº can take place. b. How much kinetic energy is carried off by the products? Heisenberg's uncertainty principle for energy and time is given by: h ΔΕΔts 211 Show that the range, D, of the exchange particle with a velocity approximately equal to the speed of light, c, that mediates a given fundamental force is given by: h Dz 2nmc a. b. If the mass of the mediating particle for the strong force is 140 MeV/c?, calculate a value for the approximate range of the strong force.
