Answer: 4 times
R=ρL/A
now length=2L
A=A/2
SO new reistance R1=ρ2L/A/2
R1=4ρL/A
R1=4(ρL/A)
SO new reistances almost increase by 4 times
Hope it helps u !!

Answer:
If the length of the conductor is doubled then the resistance would increase by 8 times. Since length becomes 2l and the cross-sectional area becomes 14th.
Hence, Almost the new resistance of the conductor increases by 4 times.
