V=Vo(Z/n)               ( Z is atomic number and n is principal qualtam number)


 Vo=2* 10^6m/s


  V=Vo3/2          (Z for li is 3)


V=9*10^6m/s................1


V=wR 


R( radius) for nth orbit is R=Ro(n^2/Z)


  Ro=52.9pm=5.29*10^-11m


R(for second orbit) =7.06*10^-11m


w = v/r


   =1.27*10^17 revolutions/sec........2
