हिन्दीTwo particles of masses \( 2\text{ kg} \) and \( 3\text{ kg} \) are placed at a distance of \( 1.0\text{ m} \) apart on the \( x \)-axis. The distance of their centre of mass from the \( 2\text{ kg} \) mass is:
View Answer & Solution
Correct answer · Option C
\( 0.6\text{ m} \)
Explanation
Taking the \( 2\text{ kg} \) mass at \( x=0 \), \( X = \frac{m_1(0) + m_2(d)}{m_1 + m_2} = \frac{3(1.0)}{2 + 3} = \frac{3}{5} = 0.6\text{ m} \).
