Question
In determination of young modulus of elasticity of wire, a force is applied and extension is recorded. Initial length of wire is ′1m′. The curve between extension and stress is depicted then Young modulus of wire will be :
Options
A.2 × 109 N/m2
B.1 × 109 N/m2
C.2 × 1010 N/m2
D.1 × 1010 N/m2
Solution
= Slope of curve
∵ L = 1 ∴ Y = 2 × 109 N/m2
