Question

A mass on a spring that has been compressed 0.1 m has a restoring force of 20 N. What is the spring constant?

Answer 1

When a mass on a spring that has been compressed 0.1 m has a restoring force of 20 N , then the value of spring constant (k) :-

200 N/m

Explanation:

Spring Constant :

According to Hooke's law, The force required to compress or extends spring is directly proportional to the distance it is compressed or stretched.

Given

x = -0.1 m

F  = 20 N

F - -kx

k  = -f/x

    = -20 / -0.1 = 200 N/m

The value of spring constant is 200 N/m.
