If a disc is made to oscillate from a point 
away from center and the axis of oscillation is perpendicular to the plane of disc, then the length of equivalent simple pendulum will be:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The length of the equivalent simple pendulum is given by:
For a disc oscillating about an axis at a distance 
from the center, the moment of inertia 
about the pivot point is:
The distance 
is 
. Thus:
