Exercise 7

(a) Write an expression relating the kinetic energy KE of the electron and the potential energy PE in the Bohr model of the hydrogen atom. (b) Suppose a hydrogen atom absorbs a photon of energy E , resulting in the transfer of the electron to a higherenergy level. Express the resulting change in the potential energy of the system in terms of E. (c) What is the change in the electron's kinetic energy during this process
