A beam of electrons with energy 250 MeV is elastically scattered through an angle of 10° by a heavy nucleus that is at rest. It is found that the differential cross-section is 65% of that expected for scattering from a point-nucleus. Estimate the root mean square radius of the nucleus. Neglect the recoil of the nucleus and use the rest mass of the electron as 0.511 MeV/c2.
