Recall the Bohr model of the hydrogen atom (1910), in which the electron is assumed to move around a circle with radius r. The model is based on two equations: (1) Newton's 2nd law for circular motion, and (2) Bohr's hypothesis of quantized angular momentum. (A) For quantum number n = 2, what is the electron speed? (B) Again for n = 2, what is the electron energy in electron-volts?
