Thanks for the question. please find the answer below:
If the length of a potentiometer wire is increased the balance point will increase.
The balance point would keep increasing if the length of the potentiometer wire would be increased.
A potentiometer is a three-terminal resistor that uses a sliding or rotating contact to form an adjustable voltage divider.

Answer:
I don't know whether I'm correct or not but the balancing length will increase by 4 times .
Explanation:
We know,
E1/E2=L1/L2
IR1/IR2=L1/L2
R1/R2=L1/L2
ρL3/A1 * A2/ρL4=L1/L2
L3/A1 * A2/2L3=L1/L2
A2/A1 * 1/2=L1/L2
If volume is constant,
VL3/VL4*1/2=L1/L2
Solving them ...
L1/L2=1/4
Hence, L2=4L1
