Pre-Test YOUNG'S MODULUS OF ELASTICITY (M2)

"If the tensile force applied to a spring does not exceed the elastic limit of the material, then the extension of the spring is proportional or directly related to the tensile force." This is the statement of which law?

• Young's Law

• Hooke's Law

• Ohm's Law

• Kirchhoff's Law

What is meant by Young's modulus?
