Question
The force required to stretch a spring varies with the distance as shown in the figure. If the experiment is performed with above spring of half length, the line 
will
- Shift towards F-axis
- Shift towards X-axis
- Remain as it is
- Become double in length
The correct answer is: Shift towards F-axis
When the length of spring is halved, its spring constant will becomes double
Slope of force displacement graph gives the spring constant 
of spring
If 
becomes double then slope of the graph increases 
graph shifts towards force- axis
