A bimetallic strip of thickness $$2cm$$ consists of zinc and silver riveted together. The approximate radius of curvature of the strip when heated through  $$500C$$ will $$be(given$$ α$$1$$,α$$2$$ are coefficients of linear expansion of $$zinc=32$$×$$10$$−$$6/C$$  $$0$$ and $$silver=19$$×$$10$$−$$6/C$$  $$0)$$
