A) OA
B) OB
C) OC
D) OD
Correct Answer: A
Solution :
\[Y=\frac{F\times l}{A\times \Delta l}\]or \[\frac{F(\operatorname{lo}ad)}{\Delta l(elongation)}=\frac{YA}{l}\] or \[slope\propto A\] or \[slope\propto {{r}^{2}}\] For thinnest wire slope is minimum. ie, wire OA is thinnest.You need to login to perform this action.
