Young's modulus is determined by the equation given by Y = 49000(m/ℓ) dyne/cm² where m is the mass and ℓ is the extension of wire used in the experiment. Now error in Young modules (Y) is estimated by taking data from m-ℓ plot in graph paper. The smallest scale divisions are 5 g and 0.02 cm along load axis and extension axis respectively. If the value of m and ℓ are 500 g and 2 cm respectively then percentage error of Y is :
