Two blocks of masses m1 = 4 kg and m2 = 6 kg are connected by a string of negligible mass passing over a frictionless pulley as shown in the figure. The coefficient of friction between block m1 and the horizontal surface is 0.4. When the system is released, the masses m1 and m2 start accelerating. What additional mass m should be placed over mass m1 so that the masses (m1 + m) slide with a uniform speed?
- a)9 kg
- b)10 kg
- c)11 kg
- d)12 kg
Correct answer is option 'C'. Can you explain this answer?

When the masses are accelerating, there is a tension in the string. When a mass m is added to m1 such that the acceleration is zero, the system of masses (m1 + m) will slide on the surface with a uniform speed and then, there is no tension in the string. This will happen if the downward force m2g equals the force of friction μ(m1 + m)g on blocks m1 and m.
11 kg
Hence, the correct choice is (c).
11 kgHence, the correct choice is (c).
