A thin wire of specific material stretched taut has a length of 36 mm and a cross-sectional area of 0.01 mm^2. The resistance is 1.5 Ω. The force applied to the wire is increased so that the length further increases by one third and the cross-sectional diameter decreases by 0.08 mm. Find the Gauge Factor if the resistivity of material is approximately 5 x 10⁻⁷ Ω-m.
