Question

A load of 15 N attached to a spring that is hanging vertically stretches the spring 35 cm. What is the spring constant of the spring?

Answer 1

The spring constant of the spring is `-42.85 N//m`.

Explanation:

Force `F=-kx`
`=>k=-F/x`
Substituting the values we get,
`k=-(15N)/(0.35m)=-42.85N//m`.
