Question : 39 of 78
Marks: +1, -0
A force acts on a body and displaces it by a distance SS in a direction at an angle θ\theta with the direction of force. What should be the value of θ\theta to get the maximum positive work?
Solution:  
We know,
W=FScos⁡θW = FS \cos \theta
Thus, the value of θ\theta to get the maximum positive work should be 0∘0^{\circ} .
As cos⁡0∘=+1\cos 0^{\circ}=+1
