Laws Of Motion

As shown in the figure, a force $F$ is applied on a block of mass $\sqrt{3} \mathrm{~kg}$ placed on a rough horizontal surface. The maximum value of $F$ for the block not to move is (Coefficient of static friction between the block and the

surface is $\frac{1}{2 \sqrt{3}}$ and acceleration due to gravity $\left.=10 \mathrm{~ms}^{-2}\right)$
