Four wires of the same material are stretched by the same load. Which one of them will elongate most if their dimensions are as follows

View answer and explanation

Correct option: A

L = 100 cm, r = 1mm

Option A (L = 100 cm, r = 1mm) will elongate most because elongation is proportional to length and inversely proportional to the area (square of the radius).
