Detailed Solution

When the system is at rest,

$m_{B} g = ρ_{L} V_{i} g$

$\Rightarrow V_{i} = \frac{m_{B}}{ρ_{L}}$

When the system is accelerating,

$m_{B} (g + \frac{g}{3}) = ρ_{L} V_{i}^{'} (g + \frac{g}{3})$

$\Rightarrow V_{i}^{'} = \frac{m_{B}}{ρ_{L}}$

so, fraction of volume immersed does not change.
