One end of a metal wire is fixed to a ceiling and a load of 2 kg hangs from the other end. A similar wire is attached to the bottom of the load and another load of 1 kg hangs from this lower wire. Then the ratio of longitudinal strain of upper wire to that of the lower wire will b e ____. [Area of cross section of wire = 0.005 cm², Y = 2 × 10¹¹ N m⁻² and g = 10 m s⁻²]
