The graph gives the moment of inertia I of a uniform 1.5 kg rod about an axis perpendicular to the rod at distance r from one end. Mark the correct statement(s).
Options:
Answer:
A,B
Solution:
For a uniform rod, I(r)=Icm+M(r-L/2)².
At r=0, ML²/3=8, with M=1.5 kg, so L=4 m.
Hence r₀=L/2=2 m and I₀=ML²/12=2 kg m².
Therefore A and B are correct.
