Question

a body totally immersed in water is raised in the water by a height h. the density of body is d and the density of water is do while the volume of the body is v and d>do which of the given

Answer 1

The body immersed will change potential energy of body and do not change the potential energy of water.

As there is raise of water by h height, which means that there is increase in the potential energy of body as it is immersed.

But there is no net work done is zero in uplifting the body. Therefore the potential energy of water remains same as before the immersed body.

And there is hydrostatic force in the water which is acting on the body.

So, the potential energy of body increase and remain same for water.
