Ernst Rutherford discovered the atomic nucleus by shooting alpha particles (helium nuclei) at gold atoms. An alpha particle (charge +2e, mass M) is approaching a gold nuclei (charge +Q) straight on. The alpha particle slows down and turns around at point B which is a distance W from the gold nuclei. Point A is 3W from point B. What is the kinetic energy of the alpha particle as it passes point A? Treat the gold nuclei as stationary. Hint: label the lengths. A OKQe W O 6KQe W O 3 KQe 2 W KQe 2W O 2KQe W B +Q
