Question

State following four properties each of alpha, beta and gamma radiations:
1. nature,
2. charge,
3. mass, and
4. effect of electric field.​

Answer 1

Answer:

α

positive charge particles; attracted towards negatively charged plate in electric field; Alpha particles are helium nuclei; mass 4 amu.

β

Beta particles are negatively charged attracted towards positively charged plate in electric field; Beta particles are fast moving electrons with a very low mass and so have a high charge to mass ratio; mass about 1/2000 of proton.

γ

Gamma rays are unaffected by an electric field; they are uncharged gamma particles are photon; practically massless.
