Question
CBSEENPH11018108

A wire increases by 10–3 of its length, when a stress of 108N/m2 is applied on it. What is the Young's modulus of material of wire?

Solution

Given,
Wire is increased of it's length, i.e., strain = 10-3 
Stress = 108N/m2

 Young's modulus = StressStrain= 10810-3= 1011 Nm-2
