Question

To determine the Young’s modulus of a wire, the formula is $Y=\frac{F}{A}\times \frac{L}{\Delta L}$ : where $L$ = length, $A$ = area of cross-section of the wire, $\Delta L$ = change in length of the wire when stretched with a force $F$. The conversion factor to change it from $CGS$ to $MKS$ system is

Answer 1

Answer: 0.1

$Y=\frac{F}{A}.\frac{L}{\Delta L}=\frac{dyne}{c{m}^2}=\frac{10^{-5}N}{10^{-4}{m}^2}=0.1N/m^2$
