Two metallic wires P and Q have same volume and are made up of same material. If their area of cross sections are in the ratio 4 : 1 and force F1 is applied to P, an extension of delta l is produced. The force which is required to produce same extension in Q is F2. Find the ratio of F1 and F2. JEE 2024
