Vedclass · Answer

(B) To keep the block at rest on the smooth inclined plane,the forces acting on the block must be balanced.Along the inclined plane,the component of the gravitational force acting downwards is $mg \sin 37^{\circ}$.The horizontal force $F$ is applied,and its component along the inclined plane acting upwards is $F \cos 37^{\circ}$.For the block to be in equilibrium,these two forces must be equal:$F \cos 37^{\circ} = mg \sin 37^{\circ}$Using the values $\cos 37^{\circ} = \frac{4}{5}$ and $\sin 37^{\circ} = \frac{3}{5}$:$F \left( \frac{4}{5} \right) = mg \left( \frac{3}{5} \right)$$F = \frac{3 mg}{4}$

$A$ block of mass $m$ is placed on a smooth fixed inclined plane with an angle of inclination of $37^{\circ}$. $A$ horizontal force $F$ is applied to keep the block at rest. Find the value of $F$.
