Explanation:
The net force of the spring is basically the force exerted on the spring by Hooke's law and the weight of the object.
Hooke's law states that:
where:
#F# is the force applied in newtons
#k# is the spring constant
#x# is the extension of the spring
So we get:
The weight of the object is:
So, the total net force on the object is:
