NCERT · Class 11 · Physics · Mechanical Properties of SolidsTwo wires A and B are made of the same material. Wire A has twice the length and twice the radius of wire B. The ratio of Young's modulus of wire A to wire B is:
Step-by-Step Solution
Young's modulus depends only on the material of the wire and not on its dimensions. Since both wires are made of the same material, the ratio is $1:1$.
