What is the Value of the Spring Constant?
You need to make a spring scale to measure the mass of objects hung from it. You want each 1.5cm length along the scale to correspond to a mass difference of 0.10 kg.
What should be the value of the spring constant?
In a spring scale:
mg = kx
Solve for k:
k = mg/x
= (0.100 kg x 9.81 m/s2) / (0.015 m)
k= 65 N/m
