In an atom, two electrons move around nucleus in circular orbits of radii ( R) and ( 4R) . The ratio of the time taken by them to complete one revolution is :

A

`1:4`

B

`4:1`

C

`1:8`

D

`8:1`

Text Solution

Verified by Experts

The correct Answer is:
C
`r_(1)/r_(2)=n_(1)^(2)/n_(2)^(2)=1/4 implies n_(1)/n_(2)=1/2 implies T_(1)/T_(2)=n_(1)^(3)/n_(2)^(3)=1/8`
