The force constant of the wire is .
Explanation:
Given that,
Mass of the load, m = 10 kg
Stretching in the spring due to weight, x = 2 mm = 0.002 m
We need to find the force constant of the wire. As the load is suspended on a wire, the force of gravity is balanced by the force acting on the spring such that,
k is the force constant of the wire
So, the force constant of the wire is . Hence, this is the required solution.
