Class 11PhysicsNewton's Laws of Motion and FrictionKinetic Friction and Motion on Rough Horizontal Surface
DifficultTwo blocks of masses $M_1$ and $M_2$ are connected with a string passing over a pulley as shown in the figure. The block $M_1$ lies on a horizontal surface. The coefficient of friction between the block $M_1$ and the horizontal surface is $\mu$. What additional mass $m$ should be placed on the block $M_1$ so that the system does not accelerate?
- A$\frac{M_2 - M_1}{\mu}$
- B$\frac{M_2}{\mu} - M_1$
- C$M_2 - \frac{M_1}{\mu}$
- D$(M_2 - M_1)\mu$
