The potential energy is $= 0.0045 J$

#### Explanation:

The maximum potential energy is when the spring is fully compressed

The spring constant is $k = 10 N {m}^{-} 1$

The displacement is $x = 0.03 m$

The potential energy is ${E}_{p} = \frac{1}{2} k {x}^{2} = \frac{1}{2} \cdot 10 \cdot {0.03}^{2} = 0.0045 J$
