hey mate here is ur ans


the resistivity remains unchanged
(as it doesn't depend on size shape of the
conductor only the nature of material and temperature )

we know that length and resistance are directly proportional
so as length is doubled resistance is also doubled so new resistance =1*2=2 ohm

hope it helps you
