A beam of α\alphaα-particles and β−\beta^-β−-particles is incident at right angles to a uniform magnetic field. Which statement about the deflection of the particles in the field is correct?
α\alphaα-particles deflect, but β−\beta^-β−-particles do not deflect.
Both α\alphaα-particles and β−\beta^-β−-particles deflect in the same direction.
α\alphaα-particles deflect in the opposite direction to β−\beta^-β−-particles.
Both particles continue in a straight line without deflecting.
