Answer: The correct answer is Option b.
Explanation:
Young's Modulus is defined as the ratio of stress acting on a substance to the amount of strain produced.
Stress is defined as force per unit area and strain is defined as proportional deformation in a material.
The equation representing Young's Modulus is:
[tex]Y=\frac{F/A}{\Delta l/l}=\frac{Fl}{A\Delta l}[/tex]
where,
Y = Young's Modulus
F = force exerted by the weight
l = length of wire
A = area of cross section
[tex]\Delta l[/tex] = change in length
Hence, the correct answer is Option b.
