Simple Harmonic Motion

A 0.1 kg mass is suspended from a wire of negligible mass. The length of the wire is 1 m and its cross-sectional area is 4.9 × 10−7m2. If the mass is pulled a little in the vertically downward direction and released, it performs simple harmonic motion of angular frequency 140 rads-1. If the Young’s modulus of the material of the wire is n × 1069Nm−2 , the value of n is _____.
