The moment of inertia of a thin rod of mass M and length L, about an axis perpendicular to the rod at a distance ¼ th from one end

a
ML26
b
3ML28
c
7ML224
d
7ML248

detailed solution

Correct option is D

moment of inertia about mid point ML212  from one end L/4 means from center also it is L/4 applying parallel axis theorem I=ML212+M L216= 7ML248
