Answer:
If displacement is parallel to the direction of force, then θ = 0
0
and hence W = F.s Cos0 = F.s ∗ 1 = F.s which is maximum/
Hence work done is said to be maximum when the angle is zero degrees.

i) Maximum work:- The angle between force and displacement should be θ = 0°
ii) Minimum work:- The angle between force and displacement should be θ = 90°
