A system consists of three masses \( m_{1}, m_{2} \) and \( m_{3} \) connected by a string passing over a pulley \( P \). The mass \( m_{1} \) hangs freely and \( m_{2} \) and \( m_{3} \) are on a rough horizontal table (the coefficient of friction \( =\mu \) ). The pulley is frictionless and of negligible mass. The downward acceleration of mass \( m_{1} \) is (Assume \( m_{1}=m_{2}=m_{3}=m \) )
(1) \( \frac{g(1-g \mu)}{9} \)
(2) \( \frac{2 g \mu}{3} \)
(3) \( \frac{g(1-2 \mu)}{3} \)
(4) \( \frac{g(1-2 \mu)}{2} \)
