Question

For any H like system, the ratio of velocities of I, II & III orbit i.e. V,:V,:V, will be
A) 1:2:3
B) 1 : 1/2 : 1/3
C) 3:2:1
D) 1:1:1​

Answer 1

Answer:

Velocity is inversely proportional to orbit number.

Vαn1​

Thus, the ratio of velocities of orbit I, II and III is given as:

11​:21​:31​

Hence, the correct option is B
