Consider two point masses

m_1

and

m_2

connected by a light rigid rod of length

r_0

. The moment of inertia of the system about an axis passing through their centre of mass and perpendicular to the rigid rod is given by

Options

A $\frac{m_1 m_2}{2\left(m_1+m_2\right)} r_0^2$
B $\frac{m_1 m_2}{m_1+m_2} r_0^2$
C $\frac{2 m_1 m_2}{m_1+m_2} r_0^2$
D $\frac{m_1^2+m_2^2}{m_1+m_2} r_0^2$

Correct answer

B. $\frac{m_1 m_2}{m_1+m_2} r_0^2$
