A nucleus X of mass M. initially at rest undergoes alpha decay according to the equation
`_(Z)^(A)Xrarr._(Z-2)^(A-4)Y+._(2)^(4)He`
The alpha particle emitted in the above process is found to move in a circular track of radius r in a uniform magnetic field B. Then (mass and charge of `alpha` particle are m and q respectively)

Options

A. The ratio of kinetic energies of the alpha particle and (doughether nucleus Y approximately equals `(M-m)/(m)`
B. the ratio of kinetic energies of the alpha particle and the doughter nucleus Y apporximately `(m)/(M)`
C. The enetgy relased in the process approximately equals `(M)/(M-m)(r^(2)q^(2)B^(2))/(2m)`
D. The energy released in the process apporximately equals `(M)/(M-m)((r^(2)q^(2)B^(2))/(2m))`

Answer

A, C
