Calculate the moment of inertia of the earth about its diameter taking it to be a sphere of `10^(25)kg `and diameter 12800 km

Text Solution

Verified by Experts

Given: `M=10^(25)kg`
`R=6400kgm=6.4xx10^(-6)m`
M.I of the earth about its diameter
`I=2/5MR^(2)`
`=2/5xx10^(25)xx(6.4xx10^(6))^(2)`
`=1.64xx10^(38)kgm^(2)`
