A solid cylinder of mass 20 kg and radius 20 cm rotates about its axis with a angular speed 100 rad
s -1 . The angular momentum of the cylinder about its axis is
Text Solution
Verified by ExpertsThe correct answer is:
A
: Here, M = 20 kg
R = 20 cm = 20 × 
m, 
Moment of inertia of the solid cylinder about its axis is
Angular momentum of the cylinder about its axis is L =
