Vedclass · Answer

(D) For the cylinder to be in equilibrium,the net force in the horizontal direction must be zero.Let $N_A$ be the normal reaction at edge $A$ and $N_B$ be the normal reaction at edge $B$.The normal reaction at any point on the surface of a smooth cylinder acts along the radius passing through that point.Resolving the normal forces into horizontal and vertical components:The horizontal component of $N_A$ is $N_A \sin 60^{\circ}$ (directed towards the right).The horizontal component of $N_B$ is $N_B \sin 30^{\circ}$ (directed towards the left).For horizontal equilibrium:$N_A \sin 60^{\circ} = N_B \sin 30^{\circ}$Substituting the values of $\sin 60^{\circ} = \frac{\sqrt{3}}{2}$ and $\sin 30^{\circ} = \frac{1}{2}$:$N_A \cdot \frac{\sqrt{3}}{2} = N_B \cdot \frac{1}{2}$Multiplying both sides by $2$:$\sqrt{3} N_A = N_B$

$A$ smooth cylinder of mass $m$ and radius $R$ is resting on two corner edges $A$ and $B$ as shown in the figure. The relation between the normal reactions at the edges $A$ and $B$ is
