An object of w and density rho is submerged in liquid of density sigma , its apparent weight will be

A block of volume V and density sigma_(b) is placed in liquid of density sigma_(1)(sigma_(1) gt sigma_(b)) , then block is moved upward upto a height h and it is still in liquid. The increase in gravitational energy of the block is :

A block of volume V and density sigma_(b) is placed in liquid of density sigma_(1)(sigma_(1) gt singma_(b)) , then block is moved upward upto a height h and it is still in liquid. The increase in gravitational energy of the block is :
