Answer:
Work done, W = 0 J
Explanation:
It is given that,
Weight of the bucket, W = F = 35 N
It is lifted vertically 3 m and then returned to its original position. We need to find the work gravity do on the bucket during this process.
Work done when the bucket is lifted vertically, W₁ = -mgh
Work done when the bucket returned to its original position, W₂ = +mgh
Net work done, W = W₁ + W₂
W = 0 J
So, the work done on the bucket is zero. Hence, this is the required solution.
