A metallic strain gauge with negligible piezoresistive effect is subjected to a strain of 50 x 10⁻⁶. For the metal, Young's Modulus = 80 GPa and Poisson's Ratio = 0.42. What is the change in resistance (in mΩ), if the unstrained resistance of the strain gauge is 200 Ω? (Round off the answer to one decimal place.)

Correct : 0.6
