A wire of length L and radius r is fixed at one end. When a stretching force F is applied at free end, the elongation in the wire is \(\text { I }\). When another wire of same material but of length 2L and radius 2r, also fixed at one end is stretched by a force 2F applied at free end, then elongation in the 2nd wire will be
- \(\frac{I}{2}\)
- \(\text { I }\)
- \(21\)
- \(\frac{I}{4}\)
Answer
(B) I
