Question

The angle between force and displacement to get maximum work is

• A. ${90}^{\circ }$
• B. ${180}^{\circ }$
• C. ${60}^{\circ }$
• D. $0^{\circ }$

Answer 1

The correct option is D $0^{\circ }$

Work done by a force F applied at an angle $\theta$ with the displacement S is given by
Work done $=F.Scos\theta$ $\text{Value of}cos\theta ismaximumat\theta =0^{\circ }asCos{0}^{\circ }=1Workdone=FS$
