when the wire is made into a circle and when 2 points int he ends of the diameter are considered then the resistor willget split up into 2
resitors each of 5 ohms and these 2 resistors will be in \\ connection
i.e..
Re=(1/5+1/5)^(-1) which we will get in substiting the \\ resistence formula
when we equate it we'll get 2.5 ohm
