Are the nucleons fundamental particles, or do they consist of still smaller parts? One way to find out is to probe a nucleon just as Rutherford probed an atom. What should be the kinetic energy of an electron for it to be able to probe a nucleon? Assume the diameter of a nucleon to be approximately 10^{-15} \mathrm{~m}.

\lambda=\mathrm{h} / \mathrm{p} and,

kinetic energy = potential energy \mathrm{E}=\mathrm{hc} / \lambda

Kinetic energy of an electron can be calculated as,

\mathrm{KE}=\mathrm{PE}=\mathrm{hc} / \lambda=10^{9} \mathrm{eV}
