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
    $90^{\circ}$

Answer

(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 $\cos 0^{\circ}=1$.
