1.	A bimetallic strip is formed out of 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 an arc of radius of curvature R. Then R is
Answer» proportional to `DeltaT` inversely proportional to `DeltaT` proportional to `abs(alpha_(B)-alpha_(C))` inversely proportional to `abs(alpha_(B)-alpha_(C))` Answer :A::B
