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, m3 are on a rough horizontal table (the co–efficient of friction = µ). The pulley is frictionless and of negligible mass. The downward acceleration of mass m1 is (Assume m1 = m2 = m3 = m)
- g(1 − gµ)/9
- 2gµ/3
- g(1 − 2µ)/3
- g(1 − 2µ)/2
Answer
