If R1 & R2 be the radius of the circular wires,
If same potential is applied on them, current in Ist will be half that in the later. If V potential is applied on them, current in them
Now magnetic field at the centre of circular
coil,
For first wire, field B1
For second wire, field B2  = 
Given B1 = B2 The given data do not provide any required result. There is a mistake in the framing of the question.
