Question
A disc of mass M and radius R is rolling with angular speed ω on a horizontal plane as shown. The magnitude of angular momentum of the disc about the origin O is : -
Options
A.
MR2ω
MR2ωB.MR2ω
C.
MR2ω
MR2ωD.2MR2ω
Solution
Angular momentum of this disc about origin
=
M(ωR) × R = MR2ω
=
M(ωR) × R = MR2ωCreate a free account to view solution
