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

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