The velocities of sound at the same temperature in two monoatomic gases of densities rho_(2) and rho_(2) are v_(1) and v_(2) respectively. If rho_(2)//rho_(2) = 4 , then value of v_(1)//v_(2) is :

Answer»

1/4
1/2
2
4

Solution :`(v_(1))/(v_(2)) = sqrt((rho_(2))/(rho_(1))) = sqrt((1)/(4))`
`(v_(1))/(v_(2)) = (1)/(2)` .
CORRECT CHOICE is (c) .
