When a block of iron floats in mercury at 0^(@) C, a fraction K_1 of its volume is submerged, while at the temperature 60^(@) C, a fraction K_(2) is seen to be submerged. If the coefficient of volume expansion of iron is gamma_(Fe) and that of mercury is gamma_(Hg) then the ration (K_1)/( K_2) can be expressed as

1.	When a block of iron floats in mercury at 0^(@) C, a fraction K_1 of its volume is submerged, while at the temperature 60^(@) C, a fraction K_(2) is seen to be submerged. If the coefficient of volume expansion of iron is gamma_(Fe) and that of mercury is gamma_(Hg) then the ration (K_1)/( K_2) can be expressed as
Answer» `( 1+ 60gamma_(FE))/( 1+ 60gamma_(Hg))` `(1-60 gamma_(Fe)) /( 1+ 60 gamma_(Hg) )` `( 1+ 60 gamma_(Fe) )/( 1- 60 gamma_(Hg) )` `( 1+ 60 gamma_(Hg))/( 1+ 60 gamma_(Fe) )` Answer :D
