Answer:
3.4 × 10⁷ N / m² .
Explanation:
Given :
Diameter of wire = 3 mm or 3 / 2 × 10⁻³ m
Length of wire = 4 m
Force = 10 N
Change in length = 2.5 mm or 2.5 × 10⁻³ m
Cross section area = π ( 3 / 2 × 10⁻³ )² m²
We know :
Y = F / A × L / Δ L
Y = 10 / π ( 3 / 2 × 10⁻³ )² × 4 / 2.5 × 10⁻³ N / m²
Y = 3.4 × 10⁷ N / m² .
