A 7 Li nucleus with a charge of +3 e and a mass of 7 u and a proton with a charge of + e and a mass of 1 u are both moving in a plane perpendicular to a magnetic field . The two particles have the same momentum. The ratio of the radius of curvature of the path of the proton ( R p ) to that of the 7 Li nucleus ( R Li ) is A. R p / R Li = 3 A. R p / R Li = 1/3 B. R p / R Li = 1/7 C. R p / R Li = 3/7 D. None of these is correct.

A doubly ionized oxygen atom 16 O ++ is moving in the same uniform magnetic field as an alpha particle. The velocities of both particles are at right angles to the magnetic field. The paths of the particles have the same radius of curvature. The ratio of the energy of the alpha particle to that of the 16 O 2+ ion is A. E α /E O = 1/1 B. E α /E O = 1/4 C. E α /E O = 1/16 A. E α /E O = 4/1 A. None of these is correct.
