Question

According to bohr's theory, the angular momentum of an electron in 5th orbit is

Answer 1

According to bohr's theory, the angular momentum of an electron in 5th orbit is equal to nh/2π.

The angular momentum (mvr) of electron in nth orbit is equal to nh2π

For the electron in 5th orbit

angular momentum =mvr =5h2π

=2.5hπ

Answer :2.5h/π

Answer 2

Hii

you are welcome in my ans

Bohr postulated in his theory that

electron will rotate in that orbital whose angular momentum is equal to nh/2π

mvr = nh/2π

where n= 5

mvr = 5h/2π

mvr = 6.63*10^- 34*5/3*10^8

mvr= 2.23*5*10^-42

mvr = 11.15 * 10^-42
