A large block of ice $$10$$ m thick has a vertical hole drilled in it and is floating in a lake. The minimum length of rope required to draw a bucket full of water through the hole is. (density$$ of $$ice=900$$ $$kg/m3$$ $$)

Question

A large block of ice $$10$$ m thick has a vertical hole drilled in it and is floating in a lake. The minimum length of rope required to draw a bucket full of water through the hole is. (density$$ of $$ice=900$$ $$kg/m3$$ $$)

Force Buoyancy $$=$$ Vin dl g                Weight of the body $$=$$ Vb db g                A×$$10$$×$$900g=A$$×$$(10$$−$$x)1000g$$                $$90=(10$$–$$x)10$$                $$90=100$$−$$10x$$⇒$$10x=100$$−$$90$$                                               $$10x=10$$                              ⇒ $$x=1m$$

A large block of ice $10 m$ thick has a vertical hole drilled in it and is floating in a lake. The minimum length of rope required to draw a bucket full of water through the hole is. (density of ice $= 900 k g / m^{3}$ )
