Two point masses

m_1

and

m_2

are connected at the ends of a light rigid rod of length

l

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

Options

A $\frac{1}{2}\left(\frac{m_1 m_2}{m_1+m_2}\right) l^2$
B\left(\frac{m_1 m_2}{m_1+m_2}\right) l^2
C\left(m_1+m_2\right) l^2
D\left[m_1^2+m_2^2\right]\left(\frac{m_1+m_2}{m_1 m_2}\right) l^2

Correct answer

B. \left(\frac{m_1 m_2}{m_1+m_2}\right) l^2

Step-by-step solution
