Question

the angular momentum of an electron in a given bohr orbit is 4.5h/1.5pie the orbit is​

Answer 1

Answer:

6

Explanation

given, the angular momentum is 4.5h/1.5π   ..(1)

we know that angular momentum of an electron in agiven bohr orbit is  

nh/2π  ..(2)

equate 1 and 2

nh/2π=4.5h/1.5π

    n/2=4.5/1.5

    n/2=3

        n=3×2

        n=6

∴the orbit is 6th bohr orbit
