What is the spring constant for a supermarket scale that stretches 0.01 m when a force of 4 n is applied

The spring constant for the supermarket scale is 400 N/m.

Explanation:

To calculate the spring constant, we use Hooke's Law. The formula for Hooke's law is:

where, F = Force applied on the spring = 4N

k = Spring constant = ? N/m

x = Compression or extension of the spring = 0.01m

Putting values in above equation, we get:

Hence, the spring constant for the supermarket scale is 400 N/m.
