In the normal atomic models given by Rutherford and Bohr, we assume that nucleus is stationary and electron revolves round in it with uniform speed. The motion of electron prevents it from dropping into the nucleus against the electrostatic attraction between nucleus and electron. If nucleus is attracting electron, electron is also attracting the nucleus. To prevent this attraction, nucleus should also revolve with uniform speed. What change it will create in the calculation made for position, speed, time period, energy, etc of electron ? the mass of electron should be replaced by the reduced mass. the mass of electron should not be replaced by the reduced mass. There is no effect of any kind by considering nuclear motion. the mass of electron should be replaced by the reduced mass if nucleus remains stationary.
