Vedclass · Answer

(C) In Rutherford's $\alpha$-particle scattering experiment,the fact that a few $\alpha$-particles undergo large-angle deflection indicates that the positive charge and mass of the atom are concentrated in a very small volume called the nucleus. The large-angle deflection is due to the electrostatic repulsion between the positively charged $\alpha$-particle and the positively charged,dense,and heavy nucleus. Therefore,both the heavy nature and the small size of the nucleus are responsible for this observation. Thus,the correct option is $(C)$.
