Questions
Two blocks of masses , are connected with a string passing over a pulley as shown in figure. The block lies on a horizontal surface. The coefficient of friction between the block and the horizontal surface is . The system accelerates. What additional mass m should be placed on the block so that the system does not accelerate?
detailed solution
Correct option is B
For the equilibrium of block of mass M1:Friction force, f = tension in the string Twhere T = f = μ(m+M1)gt----------(i)For the equilibrium of block of mass M2:T = M2g------------(ii)From (i) and (ii) μ(m+M1)g = M3gm = M2μ-M1Talk to our academic expert!
