In a Rutherford scattering experiment, an a-particle (charge - +2e) heads directly toward a lead nucleus (charge - +82e). The a-particle had a kinetic energy of 5.0 Mev when very far (r-) from the nucleus. Assuming the lead nucleus to be fixed in space, determine the distance of dosest approach (in fm). (Hint: Use conservation of energy with PE - K8;02. ) fm Need Help? Watch Read H
