Question

) State 2 conditions, when work done = 0, though sufficient

amount of force is applied on the object.​

Answer 1

Explanation:

when it's cos 90 °

and

displacement is 0

Answer 2

Answer:

Work done on an object is zero when :-

• When there is no displacement (S=0)

• Work done on a body is zero when the angle between the direction of force and the direction of displacement is 90° (displacement is normal to the force)

as work done = F. S cosФ

its magnitude depends on both displacement and the angle Ф.
