Four wires are madeof the same highly resistive material, cut to the same length, andconnected in series.

1. Wire 1 has resistance  and cross-sectional area .
2. Wire 2 has resistance  and cross-sectional area .
3. Wire 3 has resistance  and cross-sectional area .
4. Wire 4 has resistance  and cross-sectional area .

A voltage  is applied across the series, as shown in the figure.

Find the voltage  across wire 2.

Give your answer in terms of, the voltage of the battery.

I keep getting /50, but it's wrong, and I don't understand
