Physics Question from JEE Main 2023 · 31 January, Shift 2

For a solid rod, the Young's modulus of elasticity is 3.2×1011 Nm−23.2 \times 10^{11} \, Nm^{-2} and density is 8×103 kg m−38 \times 10^3 \, kg \, m^{-3}. The velocity of longitudinal wave in the rod will be:

  • A

    145.75×103 ms−1145.75 \times 10^3 \, ms^{-1}

  • B

    3.65×103 ms−13.65 \times 10^3 \, ms^{-1}

  • C

    18.96×103 ms−118.96 \times 10^3 \, ms^{-1}

  • D

    6.32×103 ms−16.32 \times 10^3 \, ms^{-1}
