Q1

For a solid rod, the Young's modulus of elasticity is \(3.2 \times 10^{11} \mathrm{Nm}^{-2}\) and density is \(8 \times 10^{3} \mathrm{~kg} \mathrm{~m}^{-3}\). The velocity of longitudinal wave in the rod will be:

a

\(145.75 \times 10^{3} \mathrm{~ms}^{-1}\)

b

\(3.65 \times 10^{3} \mathrm{~ms}^{-1}\)

c

\(18.96 \times 10^{3} \mathrm{~ms}^{-1}\)

d

\(6.32 \times 10^{3} \mathrm{~ms}^{-1}\)
