if 0.4 force is required to pull a body attaching to spring 0.1m from the position of equality find the spring constant?
To find the spring constant, we can use Hooke's Law, which states that the force required to stretch or compress a spring is directly proportional to the displacement of the spring from its equilibrium position.
Hooke's Law can be expressed as:
F = -k * x
Where:
F is the force applied to the spring,
k is the spring constant, and
x is the displacement of the spring from its equilibrium position.
In this case, we are given:
Force (F) = 0.4 N
Displacement (x) = 0.1 m
Let's plug in the values into Hooke's Law equation:
0.4 = -k * 0.1
To find the spring constant (k), we can rearrange the equation:
k = -0.4 / 0.1
k = -4 N/m
Therefore, the spring constant is -4 N/m.
