A steel scale gives correct reading at `t_(1)""^(@)C`. With the help of this scale the distance between two points measures `l^(') " and " t_(2)""^(@)C`. If the coefficient of linear expansion of steel is `alpha` then the actual length l between the two points is

A

`l=l^(')`

B

`l=l^(')[1+alpha(t_(2)-t_(1))]`

C

`l=l^(')[1-alpha(t_(2)-t_(1))]`

D

`l=l^(')/(1+alpha(t_(2)-t_(1))`
