#### Answer

The spring constant of the springs is 33.3 N/m

#### Work Step by Step

The compressed spring will push in the opposite direction from the applied force $F$. The stretched spring will pull in the opposite direction from the applied force $F$. We can set up a force equation to find the spring constant of each spring. $kx+kx = F$ $k = \frac{F}{2x}$ $k = \frac{2.0~N}{(2)(0.030~m)}$ $k = 33.3~N/m$ The spring constant of the springs is 33.3 N/m
