Physics Elasticity Question 109
Question: The force constant of a wire does not depend on
Options:
A) Nature of the material
B) Radius of the wire
C) Length of the wire
D) None of the above
Show Answer
Answer:
Correct Answer: D
Solution:
$ K=\frac{YA}{L}=\frac{Y\times \pi r^{2}}{L}\Rightarrow K\propto \frac{Yr^{2}}{L} $ i.e. force constant of a wire depends on young’s modules (nature of the material), radius of the wire and length of the wire.
