    Beta particle

    Explanation:

    If an alpha particle and a beta particle have the same energy, beta particle will penetrate farther into an object than alpha particle because;

    1. In air, beta particles can travel a few hundred times farther than alpha particles.

    2. Beta particles have more penetrating power than alpha particles.

    3. Alpha particle can be absorbed or stopped by an inch or less 1-2 centimeters of air or a thin piece of tissue while beta particles can be stopped or absorbed by a thin layer of Aluminium.

    4. Alpha particles loose all of their energies in a small volume easily that beta particles.

    5. Beta particles can traveled a longer distance between 2-3 meters at a speed nearly equal to that of light than alpha particles which travel a distance between 2-4 cm at a speed approximately five percent the speed of light.
