हिन्दीTwo objects of mass \( 10\text{ kg} \) and \( 20\text{ kg} \) respectively are connected to the two ends of a rigid rod of length \( 10\text{ m} \) with negligible mass. The distance of the center of mass of the system from the \( 10\text{ kg} \) mass is:
Correct answer · Option 4
\( \frac{20}{3}\text{ m} \)
Explanation
Distance of center of mass from \( m_1 \) is given by \( x_{CM} = \frac{m_2 L}{m_1 + m_2} = \frac{20 \times 10}{10 + 20} = \frac{200}{30} = \frac{20}{3}\text{ m} \).
