A 0.1 kg mass is suspended form a wire of negligible mass. The length of the wire is 1 m and its cross–
sectional area is 4.9 × 10–7 m2. 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 n × 109 Nm–2, the value of n is
