The value of angular momentum of the earth rotating about its own axis is

Options

A. `7xx10^(33) kg m^(2)//s`
B. `7xx10^(33) kg m^(2)//s`
C. `0.7xx10^(33) kg m^(2)//s`
D. zero

Answer

A

Explanation

`L=I omega`
`= (2)/(5) mR^(2)xx(2pi)/(T)`
`=(2)/(5)xx(6xx10^(24)xx6.4xx6.4xx10^(12)xx6.28)/(86400)`
`=7xx10^(33)kg m^(2)//s`.
