A cubical block is floating in a liquid with half of its volume immersed in the liquid. When the whole system accelerates upwards with a net acceleration of $\frac{g}{3}$ . The fraction of volume immersed in the liquid will be

Options:

Answer:

Solution:

$B - W = m a$

$ρ_{l} V^{'} (g + a) - ρ_{s} V g = ρ_{s} V a$

$ρ_{l} V^{'} (g + a) = ρ_{s} V (g + a)$

$\frac{V^{'}}{V} = \frac{ρ_{s}}{ρ_{l}} = \frac{1}{2}$

So it remains same.
