Two open pipes of length 25 cm and 25.5 ...

Two open pipes of length 25 cm and 25.5 cm produced 0.1 beat/second. The velocity of sound will be :-

A

255 cm/s

B

250 cm/s

C

350 cm/s

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`v=f_(1)xx50=f_(2)xx51`
`rArr f_(1)-f_(2)=(v)/(50)-(v)/(51)=0.1 rArrv=255 m//s`
