Class 11PhysicsNewton's Laws of Motion and FrictionStatic and Limiting Friction and Minimum Force Required to Move
Easy$A$ block of mass $M$ is being pulled along a rough horizontal surface. The coefficient of friction between the block and the surface is $\mu$. If another block of mass $M/2$ is placed on the block and it is again pulled on the surface,the coefficient of friction between the block and the surface will be
- A$\mu$
- B$3\mu / 2$
- C$2\mu$
- D$5\mu / 2$
