A gold nucleus is 192 fm (1 fm = 10-15 m) from a proton, which initially is at rest. When the proton is released, it speeds away because of the repulsion that it experiences due to the charge on the gold nucleus. What is the proton's speed a large distance (assume to be infinity) from the gold nucleus? (Assume the gold nucleus remains stationary.)

Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm
