Physics - NLM Question with Solution | TestHub

Block $A$ of mass $2\mathrm{kg}$ is placed over block $B$ of mass $8\mathrm{kg}$. The combination is placed over a rough horizontal surface. Coefficient of friction between $B$ and the floor is 0.5 . Coefficient of friction between $A$ and $B$ is 0.4 . A horizontal force of $10\mathrm{N}$ is applied on block $B$. The force of friction between $A$ and $B$ is $\left(g=10\mathrm{m}{\mathrm{s}}^{-2}\right)$
