STANDARD Physics Speed of Sound MCQ Question
Type: MCQ-numerical-Medium-Class 11
If the bulk modulus of water is 2100 MPa, what is the speed of sound in water?
A
1450 m s⁻¹
B
2100 m s⁻¹
C
1400 m s⁻¹
D
1200 m s⁻¹
Correct Answer
Option A
Detailed Explanation
The speed of sound in a medium is given by v = √(B/ρ), where B is the bulk modulus and ρ is the density. For water, using B = 2100 MPa and ρ = 1000 kg/m³, v ≈ 1450 m/s.
