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

Options

A $O A$
B $O C$
C $O D$
D $O B$

Correct answer

A. $O A$

Step-by-step 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.
