Question

Weight in air=240N weight in water=50N find its buouancy?

Answer 1

Answer:

190 N

Explanation:

Given : The weight of a AIR in air is 240 N and the weight in water is 50 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 - 50 N = 190 N

Therefore the buoyancy force in water is 190 N
