A beam of protons and α\alphaα-particles is incident at right angles to a uniform electric field.
Which statement about the deflection of the particles in the field is correct?
Protons deflect, but α\alphaα-particles do not deflect.
α\alphaα-particles deflect, but protons do not deflect.
Both protons and α\alphaα-particles deflect in the same direction.
Protons deflect in the opposite direction to α\alphaα-particles.
