To determine the Young's modulus of a wire, the formula is \(\gamma = \frac{F}{A} \times \frac{l}{v} .\) where l = length, A = area of cross-section of the wire, 31 = change in length of the wire when stretched with a force f . The conversion factor to change it from CGS to MKS system is
Text Solution
Verified by ExpertsThe correct answer is:
C
\(\gamma = \frac{F}{A} \cdot \frac{\Delta l}{L}\) = \(\frac{dyne}{cm^{2}} = \frac{10^{-1} N}{10^{-4} m^{2}} = 0.1 N/m^{2}\)
