A) \[2x\]
B) \[x\]
C) \[\frac{x}{2}\]
D) \[\frac{x}{4}\]
Correct Answer: D
Solution :
Spring is cut into two equal halves so spring constant of each part = 2k These parts are in parallel so \[{{K}_{eq}}=2K+2K=4K\] Extension force (i.e. W) is same hence by using \[F=kx\] Þ \[4k\times {x}'=kx\] Þ \[{x}'=\frac{x}{4}\].You need to login to perform this action.
