일반물리학 2 — Relativity: Problem 14

14 The mass of an electron is \(9.109\,381\,88 \times 10^{-31}\text{ kg}\). To eight significant figures, find the following for the given electron kinetic energy: (a) \(\gamma\) and (b) \(\beta\) for \(K = 2.000\,000\,0\text{ keV}\), (c) \(\gamma\) and (d) \(\beta\) for \(K = 2.000\,000\,0\text{ MeV}\), and then (e) \(\gamma\) and (f) \(\beta\) for \(K = 2.000\,000\,0\text{ GeV}\).
