Answer»

Apply Archimedes principle when system is at rest,

weight of the block = Buoyant force by liquid

pb V g =pLV/2 g

so

pb/pL =1/2

Now, when system accelerates upward with g/3 draw FBD of the block, Buoyant force upwards and weight downwards

Being part of the system block also goes up with g/3,

making equation from 2ndlaw of motion

Fb- Mg = Mg/3

Fb= 4Mg/3

pliquidVvolume of block immersedg = 4/3p blockVtotal volume of the block g

hence

Vvolume of block immersed /Vtotal volume of the block = 2/3
