A mass of 5 kg is hung from a copper wire of 5 mm diameter and 2 m in length. Calculate the extension produced. What should be the minimum diameter of the wire so that its elastic limit is not exceeded ? Elastic limit for copper `=1.5xx10^(9)` dyne `cm^(-2)` and Y for copper `=1.1xx10^(12)` dyne `cm^(-2)`
