Density remaining constant, if earth contracts to half of its present radius, duration of the day would be (in minutes)

A

`(3)/(4)`hour

B

6 hour

C

12hour

D

24hour

Text Solution

Verified by Experts

The correct Answer is:
A
`(T_(2))/(T_(1))=n^(5)=((1)/(2))^(5)=(1)/(32)`
`T_(2)=(24)/(32)=(3)/(4)h`.
