Question

The radiations suffers maximum deflection in a magnetic field is:

• A. $\alpha$-particles
• B. $\beta$-particles
• C. X-rays
• D. $\gamma$-radiations

Answer 1

The correct option is B $\beta$-particles

b.) Radiations which suffers maximum deflection in a magnetic field is $\beta$ particles.
Beta particles are deflected by a magnetic field in an opposite direction to alpha particles confirming they must hold a charge opposite to alpha particles. Beta particles are fast moving electrons and are thus negatively charged.
