Vedclass · Answer

(B) In the alpha-particle scattering experiment,Rutherford observed that alpha particles were deflected by the nucleus.By calculating the distance of closest approach,he estimated the size of the nucleus.The distance of closest approach $r_0$ is given by the formula $r_0 = \frac{1}{4\pi\epsilon_0} \frac{2Ze^2}{K}$,where $K$ is the kinetic energy of the alpha particle.Based on his experimental results,Rutherford concluded that the radius of the nucleus is of the order of $10^{-15} \ m$ (or $1 \ fm$).

What is the order of magnitude of the dimension of the nucleus as estimated by Rutherford?
