Answer: The work done on the object is 15 J
Step-by-step explanation:
Work is defined as the force that is causing the movement or displacement of an object.
Mathematically,

where,
W = work done on the object = ?
F = Force applied on the object = 5.0 N
d = displacement = 3.0 m
Putting values in above equation, we get:

Hence, the work done on the object is 15 J
