Recall the force applied to a spring and its extension/compression:
F = kΔx
Δx is the change in the spring's length (measured from its original length).
x = 0.7 m
x₀ = 0.4 m
Δx = x-x₀ = 0.7 m - 0.4 m = 0.3 m
F = 23 N
Substitute and solve for k:
23 = k×0.3
<h3>k = 7.67 N/m</h3>
Answer:
197.5072.
Explanation:
According to the Coulomb's law, the magnitude of the electrostatic force of interaction between two charges
and
which are separated by the distance
is given by

<em>where,</em> k is the Coulomb's constant.
For the case, when,
Then, using Coulomb's law,

For the case, when,
Then, using Coulomb's law, the new electric force between the charges is given by,
