In alpha-ray scattering experiment what would happen if(a) protons are used instead of alpha-particles.

Answer»

Solution :If protons are used INSTEAD pf `alpha`-particles , the angles of deflection would be different because the charge of a proton is HALF of the charge of an `alpha`-particle and mass is almost`1//4^(th)` of the mass of an `alpha`-particles . Angle of deflection depends on both, the charge as WELL as the mass.
