Mechanical Properties Of Solids Question 7
Question 7 - 31 January - Shift 2
For a solid rod, the Young’s modulus of elasticity is $3.2 \times 10^{11} Nm^{-2}$ and density is $8 \times 10^{3} kg m^{-3}$. The velocity of longitudinal wave in the rod will be.
(1) $145.75 \times 10^{3} ms^{-1}$
(2) $3.65 \times 10^{3} ms^{-1}$
(3) $18.96 \times 10^{3} ms^{-1}$
(4) $6.32 \times 10^{3} ms^{-1}$
