Question

This question has Statement $-1$ and Statement $-2$. Of the four choices given after the statements, choose the one that best describes the two statements.

If two springs $S_1$ and $S_2$ of force constants $k_1$ and $k_2$, respectively, are stretched by the same force, it is found that more work is done on spring $S_1$ than on spring $S_2$.

Statement $-1$: If stretched by the same amount, work done on $S_1$, will be more than that on $S_2$

Statement $-2$ : $k_1 < k_2$.

Answer

$\frac{1}{2} \mathrm{k}_{1} \mathrm{x}_{1}^{2}>\frac{1}{2} \mathrm{k}_{2} \mathrm{x}_{2}^{2}$ given force is same

$\mathrm{k}_{1} \mathrm{x}_{1}=\mathrm{k}_{2} \mathrm{x}_{2}$

$\Rightarrow x_{1}>x_{2}$

$\Rightarrow \mathrm{k}_{1}<\mathrm{k}_{2}$
