Answer:

The  drift velocity will be double.

Explanation:

According to the problem the length of the copper wire is given as l and radius of the copper wire given as r

Let the potential difference be v  volt

Now let the drift velocity is v(d)

now we know that v(d) = -eE/m τ

      we will take positive value,

v(d) = eEτ /m

Now we know that the electric field ,E = v/l

Therefore,

v(d) = eτ/m  x v/l

Therefore we can see that drift velocity is directly proportional to voltage

Therefore v(d) ∝ v

Hence we can say that if we double the voltage the drift velocity will be double.
