Fluid Mechanics Viscosity Question 185

Question: A cubical block is floating in a liquid with half of its volume immersed in the liquid. When the whole system accelerates upwards with acceleration of g/3, the fraction of volume immersed in the liquid will be

Options:

A)$ \frac{1}{2} $

B)$ \frac{3}{8} $

C)$ \frac{2}{3} $

D)$ \frac{3}{4} $

Show Answer

Answer:

Correct Answer: A

Solution:

Fraction of volume immersed in the liquid $ V_{in}=\left( \frac{\rho }{\sigma } \right)V $ i.e. it depends upon the densities of the block and liquid. So there will be no change in it if the system moves upward or downward with constant velocity or acceleration.
