Spring force belongs to the category of attachment to another body. Its magnitude is represented by which expression in this content?
A$F=mg$
B$F=\dfrac{k}{x}$
C$F=kx$
D$F=mv$
Answer & Solution
Correct answer: C. $F=kx$
The spring force is given here as $F=kx$, where $k$ is the spring constant and $x$ is the extension or compression. The other expressions correspond to different physical quantities or are incorrect here.
