Question

The velocity of alpha particles is:

Options
  • A

    0.2 * 10^8 m/s

  • B

    0.5 * 10^8 m/s

  • C

    0.3 * 10^8 m/s

  • D

    0.1 * 10^8 m/s

Explanation

Alpha particle shoots out from the nucleus with a high velocity of 0.1 *10^8 m/s.

STB Pg-331. 

This speed is higher than the typical velocity of alpha particles emitted from the nucleus.

This speed is significantly higher than what is typically observed for alpha particles.

This speed is also above the usual range for alpha particles emitted from nuclear reactions.

This is a common velocity for alpha particles emitted from the nucleus during radioactive decay.
