18. Calculate the K.E. of a neutron (rest mass 940 MeV) if its velocity is 0.8 c. (Ans. 626.6 MeV). 19. An electron (E = 0.8 MeV) moves in a uniform magnetic field in a circular path of radius 0.05 m. What is the magnetic flux density? (Ans. 0.041 T) 20. A charged particle B= is observed to travel in a circular path of radius 0.46 m under the =- influence of a magnetic field of 1 T. The charged particle is known to carry a charge of 1.6 x 1019 C. Find its mass in units of electron rest mass. Take mc = 0.5 MeV. [Hint: nIB mc = BRC (eV).] (Ans. 276 m) 18. Calculate the K.E. of a neutron (rest mass 940 MeV) if its velocity is 0.8 c.
