In which situation is the maximum possible work done?

when the angle between the force and displacement is 0°

when the angle between the force and displacement is 180°

when the angle between the force and displacement is 45°

when the angle between the force and displacement is 90°

A) When the angle between the Force (F) and Displacement (x) is 0°, because, Work done (W) is directly proportional to the Cosine of the Angle between the Force applied and the resultant displacement of the subject.

W = F•x cos ∅

If ∅ = 0°,

W = F•x = ==> Maximum Work Done.

If ∅ = 45°,

W = F•x/√2

If ∅ = 90°,

W = 0

If ∅ = 180°,

W = - F•x = ==> Minimum Work Done.
