MCQ (100)
Q31. The angular momentum (mvr) for the 6th
shell of hydrogen atom is:
(A) 3h
TT
(B) 2h
TT
(C) 2T
3h
(D) 6h
TT​

Answer 1

Answer:

Explanation:

According to Bohr's theory - Angular Momentum = mvr = nh/2π

⇒ For an Electron in M shell n is equal to =3

⇒ mvr = 3h/2π where h is Planck's constant = 6.626 × 10⁻³⁴ J-sec

substituting the value of h and solving we get mvr = 3.165 × 10⁻³⁴J-sec
