प्रश्न

Let IA and IB be moments of inertia of a body about two axes A and B respectively. The axis A passes through the centre of mass of the body but B does not. 

पर्याय

  • IA < IB

  • If IA < IB, the axes are parallel

  • If the axes are parallel, IA < IB

  • If the axes are not parallel, IA ≥ IB

उत्तर

If the axes are parallel, IA < IB

 

If axes A and B are parallel, we get

\[I_B  =  I_A  + m r^2\]

Here, r is the distance between two axes and m is the mass of the body.

\[\therefore l_A<l_B\]
