A block of mass $m$ is moving on a rough horizontal surface. The coefficient of kinetic friction between block and surface is $μ_{k}$ , The net force exerted by the surface on the block is $(g =$ acceleration due to gravity $)$

Options:

Answer:

Solution:

Given that: If body of mass $m$ moving with rough horizontal surface Kinetic fiction = u $F_{net} = f_{1}^{2} + f_{3}^{2} = (m g^{2})^{2} + (l m g)^{2}$ $F = m g 1 + μ^{2} =$ option $A$ is correct
