JEE MainPhysics
Which one of the following choices is closest to the order of
the angular momentum of the Earth (expressed in base MKS units)
associated with its rotation about its axis ?
Show answer and solution
m = 6 × 1024 kg
R = 6.4 × 106 m
I = [IMAGE] mR2
L = Iω = [IMAGE] × 6 × 1024 × (6.4 × 106)2
×[IMAGE] = [IMAGE] × 0.39 × 1034
R = 6.4 × 106 m
I = [IMAGE] mR2
L = Iω = [IMAGE] × 6 × 1024 × (6.4 × 106)2
×[IMAGE] = [IMAGE] × 0.39 × 1034
