Find velocity of wave is string A &B....

Find velocity of wave is string `A` &`B`.

Text Solution

Verified by Experts

The correct Answer is:
`50 m//sec, 25 m//sec`
`V_(1) = sqrt((10)/(4 xx 10^(-3))`
`= 50 m//sec`
`V_(2) = sqrt((10)/(16 xx 10^(-3)))`
`= sqrt((10^(4))/(16)) = (100)/(4) = 25 m// sec`.
