Assertion : The stress–strain graphs are shown in the figure for two materials A and B are shown in figure. Young’s modulus of A is greater than that of B.
Reason : The Young’s modulus for small strain is, \(\mathrm{Y}=\frac{\text { stress }}{\text { strain }}=\) slope of linear portion, of graph; and slope of A is more than that of B.
