A nuclide `A` undergoes `alpha`-decay and another nuclide `B` undergoed `beta`-decay. Then,A. All the `alpha`-paricles emitted by A will have almost the same speed.B. the `alpha`-particles emitted by B will have widely different speed.C. the `beta`-particles emitted by B will have almost the same speed.D. the `beta`-particles emitted by B may have almost the same speed. |

Answer» Correct Answer - a,d In `alpha`-decay, the entire energy is carried away by the `alpha`-particles as its kinetc energy. In `beta^(-)` -decay, the energy, the energy is shared between the `beta`-particles and the anti-neutrino. Hence, the speed of the `beta`-particle will vary, depending on the energy of the anti-neutrino. |
