Physics Question on Pressure
A body floats in a liquid contained in a beaker. If the whole system as shown in figure falls freely under gravity, then the upthrust on the body due to liquid is
A
zero
B
equal to the weight of liquid displaced
C
equal to the weight of the body in air
D
None of the above
Answer
zero
Explanation
Solution
When the whole system falls freely under gravity, then acceleration of both, body and liquid, will be zero. Therefore, up thrust on the body due to liquid is zero.
