The value of angular momentum of the earth rotating about its own axis isA. `7xx10^(33) kg m^(2)//s`B. `7xx10^(33) kg m^(2)//s`C. `0.7xx10^(33) kg m^(2)//s`D. zero

Answer» Correct Answer - A
`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`.
