The earth revolves round the sun in one year. If the distance between them becomes double, the new period of revolution will be

A

`1//2` year

B

`2sqrt2` years

C

4 years

D

8 years

Text Solution

Verified by Experts

The correct Answer is:
B

`(T_1)/(T_2)=(r/(2r))^(3/2)rArrT_2=2sqrt2T_1`
`rArrT_2=2sqrt2` years.
