A cubical block is floating in a liquid with one third of it's volume immersed in the liquid. When the whole system accelerates upwards with acceleration of $g /2$ .

Options:(select one or more)

Answer:

B, C, D

Solution:

If the volume immersed initially is $(V /3)$ . Then $\frac{V}{3} ρ g = m g$ (i) If the volume immersed when the system accelerates is $V$ then

$V^{'} ρ (g + \frac{g}{2}) - m g = \frac{m g}{2} \Rightarrow V^{'} = \frac{V}{3}$
