Q. The load versus elongation graph for four wires of the same materials shown in the figure. The thinnest wire is represented by the line

$OC$

$O D$

$O A$

$OB$

It is clear from the graph that, for same value of load $(F),$ elongations $l_{1}, l_{2}, l_{3}, l_{4}$ are such that
$l_{4} > l_{3} > l_{2} > l_{1}$
So, $O A$ represents the thinnest wire.
