A spring with a force constant of 50 N/m is stretched continuously from x(adsbygoogle = window.adsbygoogle || []).push({}); _{0}=0 to x_{2}=20 cm. Is more work required to stretch the spring from x_{1}=10 cm to x_{2}=20 cm than from x_{0}to x_{1}? Justify your answer mathematically.

I thought the work required is the same because the displacements are equal for both work equations... but I think I'm wrong.
