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