An electron with kinetic energy of 500 MeV is incident on a nucleus of effective radius 1 fm. (Ignore Coulomb effects in scattering and just take the nucleus to be an opaque sphere. Find the angle at which the first minimum in the scattered intensity would be found. (You can use diffraction from a circular disk. The energy is relativistic. but the deBroglie relation can be used as = h/p )
