hep with teh physics

You are presented with several wires made of the same conducting material. The radius and drift speed are given for each wire in terms of some unknown units \rm r and \rm v. Rank the wires in order of increasing electron current.

1. 2r, 2.5\ v
2. 3r, 1\v
3. 1 r, 5\v
4. 4r, 0.5 v



hep hep?

read the problem - R and V, which stand for radius and drift speed are unknown numbers.
