Question No : 9
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 |
| a) | Shift towards F-axis | b) | Shift towards X-axis |
| c) | Remain as it is | d) | Become double in length |
Answer No : 9
(a)When
the length of spring is halved, its spring constant will becomes double Slope
of force displacement graph gives the spring constant  of springIf
 becomes double then slope of the
graph increases  graph shifts towards force- axis |
