Answer:
Explanation:
A force exerted over a distance to move an object is called work done. It can be written mathematically as :
[tex]W=Fdcos\ \theta[/tex]
Where
F is the magnitude of applied force
d is the displacement of body
[tex]\theta[/tex] is the angle between the force and the displacement.
The work is positive when the both force and the displacement are in same direction and it is negative when force and the displacement are in opposite direction. The work done equals zero if the force and the displacement are perpendicular to each other.
Hence, the correct option is (d) " work ".
