Two vibrating string of same length, same cross section area and stretched to same tension is made of meterials with densities `rho` and `2rho`. Each string is fixed at both ends If `v_0` represents the fundamental mode of vibration of the one made with density `rho` and `v_2` for another Then `v_1//v_2` is:
A. `(1)/(2)`
B. `2`
C. `sqrt2`
D. `(1)/(sqrt2)`

  1. Correct Answer – C
    Velocity of sound is inversely proportional to the square rood of density of the medium.
    i.e., `V.rho=`constant
    `implies(V_1)/(V_2)=sqrt((rho_2)/(rho_1))=sqrt((2rho)/(rho))=sqrt2`
