Question 28 of 118

Young's modules of material of a wire of length LL and cross-sectional area AA is Y.Y. If the length of the wire is doubled and cross-sectional area is halved then Young's modules will be:

Show answer and solution

Answer: (C) YY

Young’s modulus depends on the material not length and cross-sectional area. So Young’s modulus will remain same irrespective of the dimension of the wire.
