Question

06 A block of volume V and of density d is placed in liquid of density d1 (d1 >d), then block is moved upward upto a height and it is still in liquid. The increase in gravitational potential energy of the system is

Answer 1

Answer:

mass of block (m)=volume×density=V×S

b

⇒ m=S

b

V

Since, we know that gravitational potential energy of block at height h

=mgh

So, the gravitational potential energy of the block =S

b

V

g

h
