Question

1.Weight of an air in air is 240N and weight in water is 190N.Find out the buoyancy

Answer 1

Answer:

Explanation:

Given : The weight of a AIR in air is 240 N and the weight in water is 190 N.

To find : The buoyancy from water.

solution : according to Archimedes principle,

apparent weight = weight of object in air - Thrust force (The buoyancy force)

here apparent weight means weight of AIR in a fluid.

so, The buoyancy force = weight of a AIR in air - weight of AIR in a fluid.

so the buoyancy force from water = weight of the AIR in air - weight of the AIR in water

= 240 N - 190 N = 50 N

Therefore the buoyancy force in water is 50 N

Answer 2

Weight of the body in air = 240 N

weight in water = 190N

Buoyancy = weight of the body in air - weight of the body in water

= 240 - 190

50 N
