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