Homework Statement
This is not a numerical problem.
A body floats in a liquid contained in a beaker. The whole system falls freely under gravity. The upthrust on the body due to liquid is:
1. zero
2. equal to weight of the liquid displaced
3. equal to the weight of the body in air
4. equal to the weight of the immersed portion of the body.
Homework Equations
The Attempt at a Solution
Since system is in free fall, the body's apparent weight becomes zero. Since the body is not exerting any force on the liquid, therefore the liquid will not be displaced, and no boyant force will act on the body.
However, I may be wrong, as boyant force depends on density (mass/vol).
