Equation to use:
F = kx
F = Force (N)
k = spring/force constant
x = displacement (m)
Known:
F = 50 N
x = 10 cm ---> 0.1 m
^^^To use the equation F = kx you must convert x into meters
Plug in what you know to the equation F = kx
50 = 0.1k
Now solve for k
k = 500 N/m
The spring constant is 500 N/m
Hope this helped!
