HELP ASAP !

Which of the following situations would result in no work done by the force indicated?

a
The object undergoes only a slight displacement while the force is acting on it.
b
The force is perpendicular to the displacement of the object.
c
The force is not completely parallel to the displacement of the object
d
All of the above result in no work done by the force indicated.

Answer 1

b The force is perpendicular to the displacement of the object.

Step-by-step explanation:

Work is done when a force is applied on a body causing it to move in a particular direction.

Work done = Force x displacement

For work to be done, a force must applied on a body to move it through a specific distance in direction.

When force is perpendicular to the displacement of the object, the component vector resolution is 0 and the work done is 0.
