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 5g and 0.02 cm along load axis and extension axis respectively. If the value of M and ℓ are 500g and 2‌cm respectively then percentage error of Y is :
