In an experiment of determine the Young's modulus of wire of a length exactly 1m, the extension in the length of the wire is measured as 0.4mm with an uncertainty of ±0.02 mm when a load of 1kg is applied. The diameter of the wire is measured as 0.4mm with an uncertainty of ±0.01 mm. The error in the measurement of Young's modulus 
is found to be 
Nm -2 . The value of x is _______ [Take g = 10m/s 2 ]
Text Solution
Verified by ExpertsThe correct answer is:
2
(2)
L=1m
L = 0.4 x 10 -3 m
m= 1kg
d=0.4x 10 -3 m
