A bimetallic strip is formed out of two identical strips, one of copper and the other of brass. The coefficients of linear expansion of the two metals are `alpha_(c)` and `alpha_(B)`. On heating, the temperature of strip increases by `DeltaT` and the strip bends to form an arc of radius R. Then R is proportional to

A

`Delta T`

B

`(1)/(Delta T)`

C

`sqrt( Delta T)`

D

`( 1)/( sqrt( Delta T) )`
