Answer:
In case of negative work, the force and displacement will be in opposite direction. It is possible when the angle between the force and displacement is .
Work done, W = FS cosθ
Here, θ = 180º and cos 180º = –1
Thus, work done, W = –FS
Here, F is force and S is displacement.
Hence, the correct answer is option D.
