"If a spring (on horizontal surface) is pressed down by 10N force the max. compress is 1m. What is the : a)Work done b)Potential energy gained by spring?"

First of all I found 10=k x 1 k=10N/m

Then work done W=F.x=10.1=10C

Ep=kX^2/2=10x1/2=5C

As a result Energy gained is half of the work done.Is it correct? Where is the other half of work?

THX! THX! THX!
