Question

The angular momentum of an electron in 4th orbit is 2 x 10-34 js, then its angular momentum in 5th orbit is
(A) 5 x 10-34 Js
(B) 2.5 x 10-34 Js
(C) 10 x 10-34 Js
(D) 2 x 10 34 Is​

Answer 1

I hope this will help you

plz mark me brainlist

Answer 2

Answer:

b.

Explanation:

angular momentum= nh/2π

2 x 10 ^-34 = 4h/2π

h/π =10^-34

5th orbit,L=5 X h/2π

=2.5 x 10^-34
