a wire is stretched by a force such that its length becomes doubled. how will the young's modulus of the material be affected

Answer» R a WIRE of LENGTH l and CROSS sectional area A stretched by a force F through a distance Δl.Then expression for Young's MODULUS is given as :-Y= FlAΔl ..........(1) According to question, Δl = 2lThen, Young's Modulus (Y)= F2A
