Answer:
1) 0° 2) 180°
Explanation:
work = FScosθ.
where, theta is the angle between F and S
For maximum work,
cos θ = 1 (1 is the greatest value in cos ratio)
cos θ = 1 when θ = 0°
therefore, for maximum work, angle between force and displacement is 0°.
For minimum work,
cos θ = -1 (-1 is the least value in cos ratio)
cos θ = -1 when θ = 180°.
therefore, for minimum work, angle between force and displacement is 180°.
