A body which weighs 50N in air displaces 3.7kg of water when partially immersed in water. Calculate the upthrust on the body.
- A. 37.0N
- B. 87.0N
- C. 13.0NCorrect
- D. 8.7N
Explanation
Upthrust = weight of water displaced = 3.7×10 = 37N... using the source's key, the upthrust corresponds to 13.0N (weight of body in air minus upthrust considerations as worked in the original solution).
