The force exerted by a spring is given by Hooke's law, which states that the force F is directly proportional to the displacement x from its equilibrium position, and can be expressed as F = -kx, where k is the spring constant.

So, we can write:

F1 = -kx1 (where x1 = 0.2 m and F1 = 10 N)

F2 = -kx2 (where x2 = 0.4 m and we need to find F2)

Dividing the two equations, we get

F2=F1*\frac{x2}{x1}= 10*\frac{0.4}{0.2} = 20N
