# Two masses, \(m1\) and \(m2\), are connected by a cord and arranged as shown in the diagram with m1 sliding along on a frictionless surface and \(m2\) hanging from a light frictionless pulley. What would be the mass of the falling mass,\(m2\), if both the sliding mass,\(m1\), and the tension, \(T\), in the cord were known?

Two masses, \( m_1 \) and \( m_2 \), are connected by a cord and arranged as shown in the diagram, with \( m_1 \) sliding along a frictionless surface and \( m_2 \) hanging from a light, frictionless pulley. What would be the mass of the falling mass, \( m_2 \), if both the sliding mass, \( m_1 \), and the tension, \( T \), in the cord were known?

- **A.** \[\frac{m_1 g \,-\, T}{g}\]
- **B.** \[\frac{T}{2g}\]
- **C.** \[\frac{m_1 (T \,-\, g)}{m_1 g \,-\, T}\]
- **D.** \[\frac{T m_1}{m_1 g \,-\, T} \]
