A nuclide `A` undergoes `alpha`-decay and another nuclides `B` undergoes `beta`-decay

Options

A. All the `alpha`-particles emitted by `A` will have almost the same speed
B. The `alpha`-particles emitted by `A` may have widely different speed.
C. All the `beta^(-)` particle emitted by `B` will have almost three same speed
D. The `beta^(-)` particles emitted by `B` may have widely different speeds

Answer

A, D

Explanation

The total kinetic energy in the process will be taken by `alpha`-particles while in `beta^(-)` particle.
