Q2. Young's modulus is determined by the equation given by $\mathrm { Y } = 49000 \frac { \mathrm {~m} } { 1 } \frac { \mathrm { dyn } } { \mathrm { cm } ^ { 2 } }$ 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 : (1) $0.5 \%$ (2) $2 \%$ (3) $0.02 \%$ (4) $0.2 \%$
