MCQ
To achieve the maximum work done, what should be the angle between the force applied and the displacement?
- A$0^{\circ}$
- B$30^{\circ}$
- C$45^{\circ}$
- D$90^{\circ}$
(a)
$0^{\circ}$
Explanation:
Maximum work is done when the force applied is in the same direction as the displacement, i.e., when the angle between the force and displacement is $0^{\circ}$. This condition aligns with the equation for work, $W = F . d . cos \theta$, where $\cos 0^{\circ}=1$.
