Question

A steel wire of length 4.5 m and cross-sectional area 3 xx 10^(-5) m^(2) stretches by the same amount as a copper wire of length 3.5 m and cross-sectional area of 1 x 10^(-5) m^(2) under a given load. The ratio of the Young's modulus of steel to that of copper is

Answer 1

Answer:

the ratio of Young's modulus of steel to that of copper is 2:3

Answer 2

Answer:

but I got ratio of 3:7

Explanation:

y depends on length and area
