What should be angle between force and displacement to get the minimum work

90°

Explanation:

This angle is the measured between the force applied and the displacement where the force vector and the displacement vector are on opposite direction.

The formula for work in this case is ;

W=F*d* cos ∅ where ;

F= force, d= distance and ∅ is the work angle

For minimum work ∅ =  90°

For maximum work ∅ = 0°

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
