A person draws water from a 5 m deep well in a bucket of mass 2 kg of capacity 8 liter by a rope of mass 1 kg. What is the total work done by the person? (g = 10 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
B
Work done to pull rope,
W 1 = 
= 
= 25 J
Work done to pull the bucket, W 2 = mgh
= 10 × 10 × 5 = 500 J
Total, W = W 1 + W 2 = 525 J
