If radius of the earth is doubled without change in its mass, what will be the length of the day?

A

`1//2`

B

2

C

4

D

`1//8`

Text Solution

Verified by Experts

The correct Answer is:
D
When the radius is doubled then volume will become 8 times the original
But density `=("mass")/("volume")=m/v`
`d=m/(8v)=1/8 (d)`
