The maximum tension that an inextensible ring of radius 1 m and mass density 
can bear is 40 N. The maximum angular velocity with which it can be rotated in a circular path is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
To find tension in the ring, let us take an arc which subtends angle 
at centre. Tangential
components of 
cancel out each other, while inward components provide the necessary centripetal force. Thus,
Here, 
linear mass density.
For small angles,
