Two rods of lengths `L_(1) and L_(2)` are made of materials whose coefficient of linear expansion are `alpha_1 and alpha_2`. If the difference between the two lengths is independent of temperature.

A

`(L_(1) // L_(2) ) = (alpha_(1) //alpha_(2) ) `

B

`( L_(1) // L_(2) ) = ( alpha_(2) // alpha_(1) ) `

C

` L_(1)^(2) alpha_(1) = L_(2)^(2) = alpha_(2)`

D

`alpha_(1)^(2) L_(1) = alpha_(2)^(2) L_(2)`
