Question

The dimension of two wires A and B are the same . But their materials are different . Their load-extension graphs are shown . If $Y_{A} a n d Y_{B}$ are the values of young's modulus of elasticity of A and B respectively then

$Y_{A} > Y_{B}$
$Y_{A} < Y_{B}$
$Y_{A} = Y_{B}$
${2 Y}_{A} = Y_{B}$
