A `0.1kg` mass is suspended from a wire of negligible mass. The length of the wire is 1m and its cross sectional are is `4.9xx10^-7m^2`. If the mass is pulled a little in the vertically downward direction and released, it performs simple harmonic motion of angular frequency `140 rad s^-1`. If the Young's modulus of the material of the wire is `nxx10^9 Nm^-2`, the value of n is
