Physics - NLM Question with Solution | TestHub

A block of mass $4\mathrm{kg}$ is placed on a horizontal surface having coefficients of static and kinetic friction as $0\cdot 5$ and $0\cdot 4$ respectively. If a force, parallel to horizontal surface of $4\mathrm{N}$ is applied to the body, then the force of friction acting on the body will be $\left[\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right]$
