Transcribed Image Text:2. Calculate the average potential and kinetic energies for the electron in the ground state of hydrogen.
Expert Solution
Step 1

The total energy of electron that revolves in an orbit is equal to sum of kinetic and potential energy.

The kinetic energy due to the motion is 

K=12mv2

where m is the mass of electron and v is the velocity. 

The potential energy due to the position is 

P=-e2r

where r is the radius and e is the charge on electron.
