Did you know?
A single strand of DNA, if uncoiled, would be ~6 feet long — yet it fits inside a cell nucleus.

Given below are two statements: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.Choose the most appropriate answer:
Both Statement (A) and Statement (R) are true and (R) is the correct explanation of (A)
Both Statement (A) and Statement (R) are true and (R) is not the correct explanation of (A)
(A) is true but (R) is false
(A) is false but (R) is true
To solve this problem, we need to evaluate the truth of the assertion (A) and reason (R) separately.Assertion (A): The stretching of a spring is determined by the shear modulus of the material of the spring.• The stretching of a spring is actually determined by the Young's modulus, not the shear modulus.• Young's modulus is a measure of the stiffness of a solid material, which is relevant for tensile (stretching) deformation.• Therefore, the assertion (A) is false.Reason (R): A coil spring of copper has more tensile strength than a steel spring of the same dimensions.
