A wire of length L\mathrm{L}L and radius r\mathrm{r}r is clamped rigidly at one end. When the other end of the wire is pulled by a force F\mathrm{F}F, its length increases by 5 cm5 \mathrm{~cm}5 cm. Another wire of the same material of length 4L4 \mathrm{L}4L and radius 4r4 \mathrm{r}4r is pulled by a force 4F4 \mathrm{F}4F under same conditions. The increase in length of this wire is ‾\underline{\hspace{2cm}}​cm\mathrm{cm}cm.
