Answer: 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:
[tex]F=kx[/tex]
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:
[tex]400N=k\times 0.01m\\\\k=400N/m[/tex]
Hence, the spring constant for the supermarket scale is 400 N/m.
