Answer :
Given data:
* The spring constant of the given spring is k = 25 N/m.
* The stretched length of the spring is x = 0.25 m.
Solution:
The magnitude of minimum force required to stretch the wire is,
[tex]\begin{gathered} F=kx \\ F=25\times0.25 \\ F=6.25\text{ N} \end{gathered}[/tex]Thus, the magnitude of minimum force required in the given case is 6.25 N.
