Answer:
The answer to your question is: letter C is correct
Explanation:
Fastest Gamma Beta Alpha Lowest
A) Alpha > Beta > Gamma
B) Gamma > Alpha > Beta
C) Gamma > Beta > Alpha
D) Beta > Gamma > Alpha
Alpha particles has the slowest speed and gamma particles have the highest speed.
What are radio active particles?
Radio active particles are those particles which are emitted during the radioactive decay of unstable radio active nuclei.
- Alpha particles are the heavier particles and have a speed of about 2× 10⁸ m/sec.
- Beta particles are comparatively lighter than the alpha particles and have a speed higher than alpha particle.
- Gamma particles are the lighter particles and have the speed of about 2.99792458 × 10⁸ m/s.
Hence the correct order of the speed of particles is gamma > beta > alpha.
