1. In the following figure, a body of mass m is tied at one end of a light string and this string is wrapped around the solid cylinder of mass M and radius R . At the moment t = 0 the system starts moving. If the friction is negligible, angular velocity at time 
would be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
We know the tangential acceleration 
[As 
for cylinder]
After time t , linear velocity of mass m , 
So angular velocity of the cylinder 
.
