give me fast please my dear bro and siso...​

Answer 1

Answer:

Explanation:

Alpha particles have a charge, so if a magnetic field is applied perpendicular to its path, the alpha particle shows some deflection.

Beta particles also have a charge. Compared to alpha particles, beta particles’ charge is half that of an alpha particles’ charge. On the other hand, speeds of beta particles are much larger than those of alpha. As a result, beta particles are deflected more strongly by magnetic fields applied perpendicular to their paths. When placed under the same magnetic field, a beta minus particle bends in the opposite direction to that of an alpha particle, while a beta plus particle would bend in the same direction as does the alpha particle.

Photons are not charged and so they do not get deflected by magnetic fields.
