A system consists of three masses m1,m2 and m3 connected by string passing over a pulley P . The mass m1 hangs freely and m2 and m3 are on a rough horizontal table ( the coefficient of friction =u ) . The pulley is frictionless and of negligible mass . The downward acceleration of mass m1 is ( Assume m1 = m2 = m3 = m ) [ AIPMT 2014 ]
