A particle of mass m, charge e, moinentuin p scatters in the electrostatic potential produced by a spherically symınctrie distribution of charge. You are given the quantity f r²pd³x = A, p(r) d*x being the charge in a vol- ume element d³r. Supposing that p vanishes rapidly as r → 0 and that S odr = 0; working in the first Born approxiination, compute the differ- ential cross scction for forward scattering. (That is lo=0, where 0 is the scattering angle.)
