a wire of resistance 10 ohm is bent to form a closed circle what is the resistance across a diameter of the circle

Resistance is directly proportional to the length of the wire.
Now when it's made into a circle the length of wire across the diameter is half of original length.
Therefore the resistance becomes half of original.
Present resistance is 10/2= 5 ohms.
Hope this helps.
