In which case there is maximum extension in the wire, if same force is applied on each wire

A

$L = 500\, cm, d = 0.05\, mm$

B

$L = 200 \,cm, d = 0.02 \,mm$

C

$L = 300 \,cm, d = 0.03 \,mm$

D

$L = 400\, cm, d = 0.01\, mm$

Solution

(d) $l \propto \frac{L}{{{r^2}}}$                   $(Y$ and $F$ are constant$)$

Maximum extension takes place in that wire for which the ratio of $\frac{L}{{{r^2}}}$ will be maximum.
