    In order to determine the Young's Modulus of a wire of radius 0.2 cm0.2\text{ }cm (measured using a scale of least count =0.001 cm= 0.001\text{ }cm ) and length 1 m1\text{ }m (measured using a scale of least count =1 mm= 1\text{ }mm ), a weight of mass 1 kg1\text{ }kg (measured using a scale of least count =1 g= 1\text{ }g ) was hanged to get the elongation of 0.5 cm0.5\text{ }cm (measured using a scale of least count 0.001 cm0.001\text{ }cm ). What will be the fractional error in the value of Young's Modulus determined by this experiment?
