The force required to stretch a spring varies with the distance a shown in the figure. If the experiment is performed with the above spring of half length, the line OA will

A

shift towards F-axis

B

shift towards X-axis

C

remain as it is

D

become double in length

Text Solution

Verified by Experts

The correct Answer is:
A

(a) `K=(F)/(x)`=slope of F-x graph.
`K prop(1)/(l)`
Length is reduced to half. Therefore, K will become two times. Slope will increase.
