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+ 60 gamma_(FE))/( 1+ 60 gamma_(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 :A
