Laws Of Motion Ques 2
- A block of mass $2 \mathrm{~kg}$ slides on an inclined plane which makes an angle of $30^{\circ}$ with the horizontal. The coefficient of friction between the block and the surface is $\sqrt{3} / \sqrt{2}$. What force along the plane should be applied to the block so that it moves (a) down and (b) up without any acceleration? (Take $g=10 \mathrm{~m} / \mathrm{s}^2$.)
