More work is done in case of the second spring.

(C) The work done $W$ in stretching a spring by a force $F$ is given by the formula $W = \frac{F^2}{2k}$.Since both springs are stretched by the same force $F$,the work done is inversely proportional to the force constant,i.e.,$W \propto \frac{1}{k}$.Given that $k_1 > k_2$,it follows that $\frac{1}{k_1} Therefore,$W_1 This implies that more work is done in the case of the second spring.
