The increase in length of a wire on stretching is 0.025%. If its Poisson's ratio is 0.4, then the percentage decrease in diameter is

The increase in length of a wire on stretching is 0.025%. If its poisson ratio is 0.4, then the percentage decrease in the diameter is :

The increase in length of a wire on stretching is 0.04% . If its Poisson's ratio is 0.5, the diameter is reduced by

The increase in length on stretching a wire is 0.05 % . If its poisson's ratio is 0.4, then its diameter

The increase in length on stretching a wire is 0.05 % . If its poisson's ratio is 0.4, then its diameter

If a copper wire is stretched to make its radius decrease by 0.1% , then the percentage increase in resistance is approximately -

If a copper wire is stretched to make its radius decrease by 0.1% , then the percentage increase in resistance is approximately -
