In a hydrogen atom, the centripetal force is furnished by the coloumb attraction between electron and proton. If a_(0) is the radius of first state orbit and permittivity of vacuum is in_(0),then the speed of the electron is.... [m = mass of electron, e = charge on electron] |

Answer» 0 `(mv^(2))/(a_(0))=(e^(2))/(4piin_(0)a_(0)^(2))` `:.v^(2)=(e^(2))/(4piin_(0)ma_(0))` `:.v=(e)/(sqrt(4piin_(0)ma_(0)))` |
