Q. Which of the following graph depicts spring constant $k$ versus length $l$ of the spring correctly
A)
B)
C)
D)
Explanation
(d) $K = \frac{F}{x}$ and increment in length is proportional the original length $i.e.$ $x \propto l\ \therefore K \propto \frac{1}{l}$
It means graph between $K$ and $l$ should be hyperbolic in nature
