From a circular ring of mass ' 
' and radius ' 
', an arc corresponding to a 
sector is removed. The moment of inertia of the remaining part of the ring about an axis passing through the center of the ring and perpendicular to the plane of the ring is ' 
' times ' 
', Then the value of ' 
' is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
If a 
arc is removed from circular ring, then mass
Mass of remaining portion, 
Moment of inertia of remaining part, 
. So, the value of 
is 
.
