A wire of length \( L \) and radius \( r \) is clamped rigidly at one end. When the other end of the wire is pulled by a force F,its length increases by \( 5 \mathrm{~cm} \). Another wire of the same material of length \( 4 \mathrm{~L} \) and radius \( 4 \mathrm{r} \) is pulled by force \( 4 \mathrm{~F} \) under same conditions. The increase in length of this wire is . \( \mathrm{cm} \)https://bit.ly/YTAI_PWAP https://www.pw.live
