Question

Statement I: The speed of sound in solids is maximum though their density is larger than liquid.
Statement II: The coefficient of elasticity of solid is large.

• A. If both Statement I and Statement II are true and the Statement II is correct explanation of the Statement I
• B. If both Statement I and Statement II are true but the Statement II is not the correct explanation of the Statement II
• C. If Statement I is true but Statement II is false
• D. If both the Statements are false

Answer 1

Answer: (A)

The velocity of sound in solid is given by, $v=\sqrt{E / \rho}$. Though $\rho$ is large for solids, but their coefficient of elasticity $E$ is much larger (compared to that of liquids and gases). That is why $v$ is maximum in case of solid.
