In two individual hydrogen atoms electrons move around the nucleus in circular orbits of radii R and 4R. The ratio of the time taken by them to complete one revolution is:

A

`4//1`

B

`4//1`

C

`8//1`

D

`(j^2)/( 2pi)`

Text Solution

Verified by Experts

The correct Answer is:
D
`(R_1)/( R_2) = (n_(1)^(2) )/( n_(2)^(2)) = (1)/(4) therefore (n_1)/(n_2) =1/2`
` (T_1)/(T_2)=((n_1)/(n_2))^3 = (1/2)^3 =1/8`
