1.	A block of volume V and of density o, is placed in a liquid of density sigma_(1)(sigma_(1) gt simga_(s)) Then the block is moved upward upto a height hand it is still in liquid. The increase in gravitational potential energy of the system is :
Answer» `sigma_(B)V_(G)H` `(sigma+sigma_(1))Vgh` `(sigma_(b)-sigma_(1))Vgh` `sigma_(1)Vgh` ANSWER :C
