Question

Calculate the velocity of an electron
placed in the third orbit of hydrogen atom. Also caculate no. of revolution per second that this electron makes around the nucleus​

Answer 1

Answer:

μn=$\sqrt{\frac{ze^{2} }{mr_{n} } )}$

Radius of 3rd orbit is=$r_{1} *n^{2}$

                                  =$0.529*10^{-8} *9cm$

μn=$\sqrt{(\frac{1*(4.083*10^{-10} )^{2} }{(9.108*10^{-28}*0.529*10^{-8}*9  }) }$

μn=$7.29*10^{7} cmsec^{-1}$
