Physics - W.E.P. Question with Solution | TestHub

Since ${\mathrm{K}}_1>{\mathrm{K}}_2,$ therefore, $\mathrm{P}$ will develop greater restoring force than $\mathrm{Q}$. So the applied force on $\mathrm{P}$ will be more than the applied force on $\mathrm{Q}$. Extension is same in both the cases. So, more work is done on $\mathrm{P}$.
