Hooke's law

The force of the spring is directly proportional to its extension.

F_s = - kx

Where, k - spring constant and x - displacement of the spring

Step 1: Note down the provided information

Spring constant k = 0.69 N/m

Initial spring length d_1=0.190m

Final spring length d_2=0.556m

Change in spring length \Delta x=d_1-d_2=0.190-0.556

\Delta x=-0.366

Step 2: Determining the spring force.

F_s = - k \Delta x

F_s=-\ 0.69*\left(-0.366\right)

F_s=0.2525

Hence, spring force on block F_s=0.2525 N
