Question 888549: IS THIS CORRECT??
The force required to compress a spring varies directly with the change in length of the spring. If a force of 20 newtons is required to compress a spring 2 centimeters, how much force is required to compress the same spring 10 centimeters?
20/2=x/10
2x=5x20
2x=100
x=100/2
x=50???

You can put this solution on YOUR website!
F=kx
k=F%2Fx
20%2F2=F%2F10

So far so good, same as your setup.
Here's the problem,
2x=5%2A20
It should be
2x=10%2A20
2x=200
x=100
