The loss in weight of a solid when immersed in a liquid at `0^@C` is `W_0` and at `t^@C` is W. If cubical coefficients of expansion of the solid and the liquid are `gamma_S` and `gamma_L`, respectively, then W is equal to

A

`w_(0) [1+ ( gamma_(s) - gamma_(l) ) t ]`

B

`w_(0) [ 1- ( gamma_(s) - gamma_(l) ) t ]`

C

` w_(0) [ ( gamma_(s) - gamma_(l) ) t ]`
