Question

Q2)A filament 0.5m long and having a cross-sectional area of 1mm²was stretched to breaking.

If the breaking stress for the filament was found to be 10⁹ Pa, calculate the mass which was hung on the filament to break it.
Assuming the filament stretched linearly up to breaking, calculate the amount by which the filament stretched. (Young’s modulus for the material = 6 x 10¹⁰ Pa)
If the assumption in (b) was justified, what might the material have been? State in one word.
