The length of the wire between two points at the ends of a diameter of a circle is
half of the whole wire. The resistance of a conductor is directly proportional to its
length.
Thus, the two resistance 5/2 ohm will be in parallel.
Let R be the effective resistance.
1/R=2/5+2/5
1/R=4/5
R=5/4=1.25 ohm.
