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 |
