A boy of mass M is applying a horizontal force to slide a box of mass M’ on a rough horizontal surface. The coefficient of friction between the shoes of the boy and the floor is \(\mu\) and that between the box and the floor is \(\mu^{\prime}\). In which of the following cases it is certainly not possible to slide the box?
- \(\mu<\mu^{\prime}\), M < M’
- \(\mu>\mu^{\prime}\), M < M’
- \(\mu<\mu^{\prime}\), M > M’
- \(\mu>\mu^{\prime}\), M > M’
Answer
(A) < ^ , M < M’
