The minimum and maximum values of Poisson's ratio for a metal lie between

For a homogeneous isotropic material, which one of the following cannot be the value of Poisson’s ratio?

The Young's modulus of the material of a wire is $6 \times 10^{12} \ N/m^2$ and there is no transverse strain in it,then its modulus of rigidity will be

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

$A$ material has Poisson's ratio $0.50$. If a uniform rod made of this material suffers a longitudinal strain of $2 \times 10^{-3}$,then the percentage change in volume is

If Poisson's ratio $\sigma$ is $-\frac{1}{2}$ for a material,then the material is
