Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The stretching of a spring is determined by the shear modulus of the material of the spring.
Reason (R): A coil spring of copper has more tensile strength than a steel spring of the same dimensions.
In light of the above statements, choose the most appropriate answer from the options given below:
  • a)
    (A) is false but (R) is true
  • b)
    Both (A) and (R) are true and (R) is the correct explanation of (A)
  • c)
    Both (A) and (R) are true and (R) is not the correct explanation of (A)
  • d)
    (A) is true but (R) is false
Correct answer is option 'D'. Can you explain this answer?

Given below are two statements: One is labelled as Assertion (A) and ...
Assertion (A): The stretching of a spring is determined by the shear modulus of the material of the spring.

Reason (R): A coil spring of copper has more tensile strength than a steel spring of the same dimensions.

Explanation:
• The Assertion (A) is true because the stretching of a spring is determined by the shear modulus of the material of the spring. The shear modulus is the ratio of shear stress to the shear strain within the elastic limit of the spring. The shear modulus determines how much the spring will stretch under a given load.
• The Reason (R) is false because the tensile strength of a material has nothing to do with the stretching of a spring. Tensile strength is the maximum stress that a material can withstand before breaking. It is not related to how much a spring will stretch under a given load.
• Therefore, option (D) is the correct answer as the Assertion (A) is true but the Reason (R) is false.

Conclusion:
• The stretching of a spring is determined by the shear modulus of the material of the spring.
• The tensile strength of a material has nothing to do with the stretching of a spring.

Given below are two statements: One is labelled as Assertion (A) and ...
Assertion (A): The stretching of a spring is determined by the shear modulus of the material of the spring.

Reason (R): A coil spring of copper has more tensile strength than a steel spring of the same dimensions.

Explanation:

- Assertion (A) states that the stretching of a spring is determined by the shear modulus of the material of the spring. This is true as the shear modulus is a measure of the stiffness of a material and it determines how much a material will deform when a force is applied to it.
- Reason (R) states that a coil spring of copper has more tensile strength than a steel spring of the same dimensions. This statement is false as steel has a higher tensile strength than copper. Tensile strength is the maximum stress that a material can withstand before breaking under tension.
- Therefore, option (D) is the correct answer as Assertion (A) is true but Reason (R) is false.

Conclusion:

- The stretching of a spring is determined by the shear modulus of the material of the spring.
- A coil spring of copper does not have more tensile strength than a steel spring of the same dimensions.
