Question

it the angle beetween force and displacement is , o then for what value of o is work done zero​

Answer 1

Answer:

are also zero answer are equall

Answer 2

Answer:

If cosθ=1, maximum amount work can be done on the body i.e. if θ=0 or the directions of F and s are parallel. If cosθ=0 then the work done on the body will be zero i.e. when the angle between the force and the displacement is 90o.
