Correct answer is (d) 6.32 × 103 ms -1

Q. For a solid rod, the Young's modulus of elasticity is $3.2 \times 1 0^{11} N m^{- 2}$ and density is $8 \times 1 0^{3} k g m^{- 3}$ . The velocity of longitudinal wave in the rod will be. s

$3.65 \times 1 0^{3} m s^{- 1}$

$18.96 \times 1 0^{3} m s^{- 1}$

$145.75 \times 1 0^{3} m s^{- 1}$

$6.32 \times 1 0^{3} m s^{- 1}$

Correct answer is (d) $6.32 \times 1 0^{3} m s^{- 1}$
