The adjacent graph shows the extra extension (Vx) of a wire length 1m suspended from the top of a roof at one end with an extra load Vw connected to the other end . If the cross sectional area of the wire is 10 to the power of negative 6 end exponent m to the power of 2 end exponent, calculate the Young’s modulus of the material of the wire.
