Question

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) [2014]
(a)g(1–gμ )/g
(b)2gμ/3
(c)g(1– 2μ )/3
(d)g(1 – 2μ )/2
