Independent of \( a \)
Independent of \( h \)
Independent of both \( a \) and \( h \)
Independent of its mass
Hide Solution
Verified By Collegedunia
The Correct Option is
B
Solution and Explanation
The moment of inertia about the cylinder's axis is: \[ I = \frac{1}{2} M a^2 \] which does not depend on \( h \), only on the radius \( a \).
