c) 4
d) 3

Text Solution

Verified by Experts

The correct Answer is:
A, B
Angular momentum of the earth about its axis `=2/5mr^2xx((2pi)/86400))`
`(because I=2/5mr^2)`
angular moment of the earth about suns axis
`=mR^2xx((2pi)/86400xx365)`
`(because I=mR^2)`
therefore, ratio of the angular momentum
`=(2/5mr^2xx(2pi/86400)/(mr^2xx2pi/(86400x365)`
`=((2r^2xx365))/(5R^2)=((2.990xx10^10)/(1.125xx10^17))`
`=2.65xx10^-7`
