The spring force is given by F = -kx, 

where k is the spring constant and x is the displacement from the equilibrium position. In this case, the spring is compressed by 0.2 m, so x = -0.2 m (since the displacement is in the opposite direction of the spring's natural lengthening direction). 

Plugging in the values, 

we get F= (-100 N/m)(-0.2m)=20N.

so the answer is 20 N.
