A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The co-efficients of linear expansion of the two metals are `alpha_(C)` and `alpha_(B)`. On heating, the the strip bends to form an are of radius of curvature `R`. Then `R` is

A

Proportional of `DeltaT`

B
