Question

the weight of a body in water is 100N. the water exerted a buoyancy of 20N. calculate the weight of the body in air???​

Answer 1

Answer:The weight of the body in air is 120 N.

Explanation:buoyancy force =Weight in air - weight in water

20N=Weight in air - 100N

Weight in air=120N

Answer 2

The weight of the body in air with negligible upthrust is equal to 120 N

Explanation:

• the weight of a body in a liquid is the difference between the weight of the body in air having negligible upthrust and the amount of upthrust provided by that particular liquid.

• the weight of a body in water is said to be 100 Newton. The buoyancy which is exerted by water is equal to 20 Newton.

• Hence the weight of the body d in air is equal to 100 + 20 Newton = 120 Newton
