alleryWhich of the radioactive radiations is not deflected by electric or magnetic fields?
AGamma rays
BBeta rays
CAlpha rays
DCathode rays
Answer & Solution
Correct answer: A. Gamma rays
1. Charged particles are deflected by electric and magnetic fields.
2. Alpha rays (+) and beta rays (-) are charged, so both get deflected.
3. Gamma rays are neutral electromagnetic waves with zero charge.
4. Being chargeless, gamma rays are not deflected by either field.
