If m_{1}> m_{2}

And I_1 And I_2 are Moment of inertia of masses m_1 and m_2 respectively about an axis passing through their COM and perpendicular to the line joining them. Then which relation is correct.

 

Option: 1

I_{1}> I_{2}  


Option: 2

I_{1}< I_{2}


Option: 3

I_{1}= I_{2}


Option: 4

As      r_{1}=\frac{m_{2}}{m_{1}+m_{2}}\ast r  and r_{2}=\frac{m_{1}}{m_{1}+m_{2}}\ast r

And     I_{1}=m_{1}r_{1}^{2} and I_{2}=m_{2}r_{2}^{2}

And     I=\frac{m_{1}m_{2}}{m_{1}+m_{2}}\ast r^{2}

And     I_{1}=m_{2}I and I_{2}=m_{1}I 

So As m_{1}> m_{2}

So,     I_{1}< I_{2}
