A) Shift towards F-axis
B) Shift towards X-axis
C) Remain as it is
D) Become double in length
Correct Answer: A
Solution :
When the length of spring is halved, its spring constant will becomes double. (because \[k\propto \frac{1}{x}\propto \frac{1}{L}\therefore k\propto \frac{1}{L}\]) Slope of force displacement graph gives the spring constant (k) of spring. If k becomes double then slope of the graph increases i.e. graph shifts towards force-axis.
