For silver,Young's modulus is $7.25 \times 10^{10} \ N/m^2$ and Bulk modulus is $11 \times 10^{10} \ N/m^2$. Its Poisson's ratio will be

Which of the following is the correct relation between Young's modulus $(Y)$ and Poisson's ratio $(\sigma)$?

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

$A$ copper wire of cross-sectional area $0.01 \ cm^2$ is under a tension of $22 \ N$. Find the percentage change in the cross-sectional area (Young's modulus of copper $= 1.1 \times 10^{11} \ N \ m^{-2}$ and Poisson ratio $= 0.32$).

There is no change in the volume of a wire due to a change in its length on stretching. The Poisson's ratio of the material of the wire is:

A compressive force is applied to a uniform rod of rectangular cross-section so that its length decreases by $1 \%$. If the Poisson's ratio for the material of the rod is $0.2,$ which of the following statements is correct? "The volume approximately ..........."
