The momentum of an electron revolving in n t h   orbit is given by : (Symbols have their usual meanings)

The momentum of an electron revolving in nth  orbit is given by : (Symbols have their usual meanings)
  1. nh2πr
  2. nh2r
  3. nh2π
  4. 2πrnh

Solution

According to Bohr's postulates, angular momentum of an electron in an orbit is given by,

L=mvr=nh2π

Therefore, linear momentum p=Lr=nh2πr
