A certain volume of copper is drawn into a wire of radius a and is wrapped in shape of a helix having radius r(>>a). The windings are as close as possible without overlapping. Self inductance of the inductor so obtained is L1. Another wire of radius 2 a is drawn using same volume of copper and wound in the fashion as described above. This time the inductance is L2. Find L1/L2
