At `4^(@)C, 0.98` of the volume of a body is immersed in water. The temperature at which the entire body gets immersed in water is (neglect the expansion of the body ) (`gamma_(w) = 3.3 xx10 ^(-4)K^(-1)`):-
A. `40.8^(@)C`
B. `64.6^(@)C`
C. `60.6^(@)C`
D. `58.8^(@)C`

Correct Answer - B
Let at temperature `theta` , volume increases by `2%` then
` 100=98[1+3.3xx10(theta-4)]`
`implies theta = 60.4 + 4 =64.4 ^(@)C`
