A) \[l\]
B) \[{{l}^{2}}\]
C) \[\frac{1}{l}\]
D) \[\frac{1}{{{l}^{2}}}\]
Correct Answer: B
Solution :
Extension \[x=\frac{Fl}{AY}\] \[\left( \begin{align} & \text{as}\,V=Al \\ & \text{so}\,A=\frac{V}{l} \\ \end{align} \right)\] \[=\frac{F{{l}^{2}}}{VY}\propto {{l}^{2}}\]You need to login to perform this action.
