The angular momentum for the electron in Bohr's orbit is L. If the electron is assumed to revolve in second orbit of hydrogen atom, then the change in angular momentum will be
A
Zero
B
2L
C
L
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Bohr's formula for angular momentum of an electron in an orbit is given by
For he first orbit, n = 1 and the angular momentum is 
For 2 nd orbit
Hence, the change in angular momentum is
L = 2L - L = L
