1.	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 the strip goes up by DeltaT and the strip bends to form a are of radius of curvature R. Then R is:
Answer» Proportional to `DELTA T` inversely proportional to `DeltaT` Proportional to `\| alpha_(B) - alpha_( C) \|` inversely proportional to `\| alpha_(B) - alpha_( C) \|` Answer :B::D
