According to Bohr’s theory, the angular momentum of electron in 5th orbit is

According to Bohr’s theory, the angular momentum of electron in 5th orbit is

Options

(a) 25 h/π
(b) 1.0 h/π
(c) 10 h/π
(d) 2.5 h/π

Correct Answer:

2.5 h/π

Explanation:

Angular momentum of aon electron= electron = mvr = nh/2π (n is the orbit number)
For 5th orbit, mvr = 5h/2π = 2.5h/π
