A system consists of three masses m₁, m₂ and m₃ connected by a string passing

A system consists of three masses m₁, m₂ and m₃ connected by a 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 = μ). The pulley is frictionless and of negligible mass. The downward acceleration of mass m₁ is (Assume m₁=m₂=m₃=m)

(b) 2gμ/3
(c) g(1-2μ)/3
(d) g(1-2μ)/2
