Q83 / 90 · JEE Main 2012 (07 May Online) · Physics

The load versus elongation graphs for four wires of same length and made of the same material are shown in the figure. The thinnest wire is represented by the line Figure

  • Correct answer
    A
    $O A$
  • B
    $O C$
  • C
    $O D$
  • D
    $O B$

Solution

From the graph, it is clear that for the same value of load, elongation is maximum for wire $O A$. Hence $O A$ is the thinnest wire among the four wires.

Hence, the correct answer is option: 'A'.
