Question

is it possible that a force is acting on a body but still the work done is zero ?Explain giving one example.​

Answer 1

Answer:

if we try pushing a large wall, it does not move. Thus, there is no dusplacement

Explanation:

and therefore the work done is zero.

Answer 2

Answer:

Yes ,it's possible

Explanation:

When the force is acting in a perpendicular direction means 90 degree.

For example:

If a man carrie a suitcase strictly horizontally ,he does no work with respect to gravity becoz the force of gravity acts vertically downward and the angle between the displacement of the suitcase and the direction of force becomes 90 degree and cos 90 degree becomes 0
