A somoneter wire resonates with a given ...

A somoneter wire resonates with a given tuning fork forming standing waves with five antindoes between the two bridges when a mass of 9 kg is suspended from the wire. Resonates with the same tuning fork forming three antindoes for the same postions of the bridges. the value of M is

A

25kg

B

5kg

C

12.5kg

D

1/25kg

Text Solution

Verified by Experts

The correct Answer is:
A
`f_0=(5)/(2 1) sqrt((9 g)/(mu))=(3)/(2 1)sqrt((M g)/(mu))implies M= 25 kg`

A sonometer wire under tension of 63 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of that sonometer wire has a length of 10 cm and a mass of 1 g. The vibrating tuning fork is now moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved if the speed of sound in air is 300 m/s.
