Vedclass · Answer

(B) In the Rutherford alpha-particle scattering experiment,the distance of closest approach is used to estimate the size of the nucleus.For an alpha particle with kinetic energy $K$ directed towards the center of the nucleus with atomic number $Z$,the distance of closest approach $r_0$ is given by $r_0 = \frac{1}{4\pi\epsilon_0} \frac{2Ze^2}{K}$.Experimental results indicate that the dimension of the nucleus is of the order of $10^{-15} \ m$ (or $1 \ fm$).

State the dimension of the nucleus from the Rutherford experiment.
