Consider the Bohr's model of a one-electron atom where the electron moves around the nucleus. In the following List-I contains some quantities for the nth orbit of the atom and List-II contains options showing how they depend on n .
 
List - I List - II
(I) Radius of the nth orbit P n-2
(II) Angular momentum of the electron in the nth orbit Q n-1
(III) Kinetic energy of the electron in the nth orbit R n0
(IV) Potential energy of the electron in the nth orbit S n1
  T n2
  U n1/2

Which of the following options has the correct combination considering List-I and List-II?
  1. II, R
  2. I, P
  3. I, T
  4. II, Q

Solution

According to Bohr’s atomic model:
Radius of orbit n2
Angular Momentum n
Kinetic energy 1n2
Potential energy -1n2
