Answer:
Total work done is 0 J
Explanation:
The body moves up the inclined plane and then down once. After coming down the body returns to its starting position.
It means that the net displacement of the object is zero.
We know that,
Work done = Force * displacement * cosine of the angle between force and displacement
Therefore,
work done = 0 J [ Since the displacement is zero ]
