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 $\frac{g}{3}$ , the fraction of volume immersed in the liquid will be

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

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