An object with a mass of #12 kg# is lying still on a surface and is compressing a horizontal spring by #1/3 m#. If the spring's constant is #4 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?

Force F required to compress a spring by x unit is
Here
hence Force exerted on the object of mass 1 kg is
This force is balanced by the then static frictional force as it is self adjusting one,
So the minimum value of the coefficient of static frictions
So
