(a) Ice floats in water with about wine-tenths of its volume submerged. What is the fraction sub merged for an iceberg floating on freshwater lake of a hypothetical) planet whose gravity is to times that of the earth? (b) What is the fractional volume submerged of an ice cube in a fall of water placed in an enclosure which is freely falling under gravity?

1.	(a) Ice floats in water with about wine-tenths of its volume submerged. What is the fraction sub merged for an iceberg floating on freshwater lake of a hypothetical) planet whose gravity is to times that of the earth? (b) What is the fractional volume submerged of an ice cube in a fall of water placed in an enclosure which is freely falling under gravity?
Answer» Solution :(a) The fractional volume submerged does not depend on the gravity. So in the PLANET also fee will get submerged upto the same level. The CONDITION for flotation is: mass of floating body mass of LIQUID displaced (B) Pressure and hence UPTHRUST depends on g. So ifg=0upthrust is zero. So the ice will float with any value for the fractional submerged volume.
