Question
A man of mass m is applying a horizontal force to slide a box of mass m′ on a rough horizontal surface. It is known that the man does not slide. The coefficient of friction between the shoes of the man and the floor is μand between the box and the floor is μ′. on which of the following cases it is certainly not possible to slide the box?
Options
A.μ > μ′, m < m′
B.μ < μ′, m < m′
C.μ < μ′, m > m′
D.μ > μ′, m > m′
Solution
When μmg < μ′m′g then man can not slide the body.
