a block of ice with an area A and a height h floats in water of density rho. what work should be performed to submerge the ice block completely into water if density of ice is rho1? any hints?
Yea.. find out how much of the ice is floating about the water.. you can easily derive that expression.. !! once you know that , its easy!
yeah. i got it already. :P thank you for replying.
one thing to be careful about in this is the force is linearly varying with how much height is above the water. so we have to integrate it. so i was missing a '2' in the denominator.
oooO... i missed that part.. yea.. its a variable force :D
