Young’s modulus of steel is . When expressed in CGS units of , it will be equal to:
a)
b)
c)
d)

Correct answer is c)

Both Dyne and Newton are force units. While Dyne is measured in the C-G-S (Centimeter – Gram – Second) system, Newton is measured in the contemporary SI system, which yields the Young’s Modulus relationship between stress and strain. It is used to determine the material’s hardness.
Here, stress refers to the force applied per unit area, while strain refers to the object’s deformation.
