Two point masses m(1) and m(2) are joine...

Two point masses `m_(1)` and `m_(2)` are joined by a weightless rod of length `r`. Calculate the moment of inertia of the system about an axis passing through its centre of mass and perpendicular to the rod.

Text Solution

Verified by Experts

The correct Answer is:
(m_(1)m_(2))/(m_(1)+m_(2))^(2)`
