A particle of mass m moves around the origin in a potential 1 2 ~m ² r ² , where r is the distance from the origin. Applying the Bohr model in this case, the radius of the particle in its n ^ th orbit in terms of a = h /(2 m ) is
Options
- Aa n
- Ban
- Ca n²
- Dan n
Correct answer
A. a n
Step-by-step solution
mvr = n h 2 v = r mr ² = n h 2 r = nh ² 2 m r = n h ² 2 m r = n a
