Question

11. Two point masses of 4 kg and 12 kg are joined by
a massless rod of length 2 m. Moment of inertia
of this system about an axis passing through its
centre of mass and normal to the rod is
(11 12 kg-m2
(2) 3 kg-m2
(3) 6 kg-m2
(4) 9 kg-m2​

Answer 1

Answer:

Explanation:

I = u * $r^{2}$

I = (4*12) / (4+12)  *  $2^{2}$

I = 12 kg-$m^{2}$
