Question

For the given figure, where does the center of mass lie?

• A. outside the mass and rod system
• B. Closer to mass $m_2$
• C. Exactly at the midpoint of the rod
• D. Closer to mass $m_1$

Answer 1

The correct option is B

Closer to mass $m_2$

For the given system of masses attached to the ends of the rod, the center of mass is closer to the heavy mass $m_2$ as it will get balanced when we move the fulcrum towards the right end. There is more distribution of mass on the right compared to the left side. So, the COM lies close to mass $m_2$.
