Physics - SHM Question with Solution | TestHub

A $0.1\mathrm{kg}$ mass is suspended from a wire of negligible mass. The length of the wire is $1\mathrm{m}$ and its cross-sectional area is $4.9\times 10^{-7}{\mathrm{m}}^2$. If the mass is pulled a little in the vertically downward direction and released, it performs simple harmonic motion of angular frequency $140\mathrm{rad}{\mathrm{s}}^{-1}$. If the Young's modulus of the material of the wire is $n\times 10^9{\mathrm{Nm}}^{-2}$, the value of $n$ is
