A metal wire having poisson ratio 1/4 and young's modulus 4×1010 N/m2 is stretched by a force, which produces a lateral strain of 0.01% in it. The elastic potential energy stored per unit volume in wire is (in J/m3)

A metal wire having poisson ratio 1/4 and young's modulus 4×1010 N/m2

1.	A metal wire having poisson ratio 1/4 and young's modulus 4×1010 N/m2 is stretched by a force, which produces a lateral strain of 0.01% in it. The elastic potential energy stored per unit volume in wire is (in J/m3)
Answer» A metal wire having poisson ratio $1 / 4$ and young's modulus $4 \times 10^{10} {N/m}^{2}$ is stretched by a force, which produces a lateral strain of $0.01 %$ in it. The elastic potential energy stored per unit volume in wire is (in ${J/m}^{3}$ )
