In a radioactive phenomenon observation is shown in the figure where α deviates less than β in some electric or magnetic field (not shown in the figure). What is the reason for less deviation?
Correct answer: C. α is heavier particle
- A. α is charged particle
- B. α is neutral particle
- C. α is heavier particle
- D. α is lighter particle
Explanation
In a magnetic or electric field, deviation occurs to the charge of a particle and how much a particle deviates depends on the mass of a particle. An alpha particle is identical to the nucleus of the Helium-4 atom. It consists of two protons and two neutrons bound together having a mass of four units and a positive charge of two. A gamma particle has no charge and no mass, hence it is undeflected. A beta particle has a negative charge and lower mass as compared to an alpha particle.Alpha particles deflect the least because it is heavier than beta and gamma.42α ,0-1β ,00γ .
