Question

a uniform rod of mass m and length 2l has two particles of mass m each at its ends. the moment of inertia of the system about an axis which passes through the centre of the rod can be :​

Answer 1

Answer:

As, axis is passing through centre of mass :

moment of inertia = reduce mass x r^2 = [(m1 x m2) /m1+m2 ] / r^2

i = (m^2 / 2m) / l^2 = ml^2 / 2
