A wire is stretched to double of its length. The strain is
- A 1
- B 2
- C 3
- D 4
Answer & Solution
Correct Answer
(A) 1
Step-by-step Solution
Detailed explanation
Strain is defined as the ratio of the change in length to the original length of the wire. Let the original length of the wire be \(L\). The wire is stretched to double its length, so the new length \(L' = 2L\). The change in length \(\Delta L = L' - L = 2L - L = L\). Strain =…
