Question

Which one of the following statements about alpha and beta particles is correct?

Options

• They carry equal amounts of charge.

• Each alpha particle has four times the mass of a beta particle.

• Only alpha particles can cause ionization.

• They can both be deflected by magnetic fields when they are in motion.

• Alpha particles have a larger range in air than beta particles.

Answer 1

They can both be deflected by magnetic fields when they are in motion.

Explanation: 

Both alpha and beta particles are electrically charged. Alpha particles carry a positive charge, while beta (β⁻) particles carry a negative charge.

Therefore, both can be deflected by magnetic fields when they are in motion.
