Answer: The correct answer is Option b.

Step-by-step 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:


Y=(F/A)/(\Delta l/l)=(Fl)/(A\Delta l)

where,

Y = Young's Modulus

F = force exerted by the weight

l = length of wire

A = area of cross section


\Delta l = change in length

Hence, the correct answer is Option b.
