A tuning fork of frequency 392 Hz , resonates with 50 cm length of a string under tension ( T ). If length of the string is decreased by 2%, keeping the tension constant, the number of beats heard when the string and the tuning fork made to vibrate simultaneously is

A tuning fork of frequency 392 Hz, resonates with 50 cm length of a string under tension T. If the length of the string is decreased by 2% keeping the tension constant the number of beats heard when the string and the tuning fork are made to vibrate simultaneously is

A stretched string is in unison with a tuning fork of frequency 392Hz. If the length of the string is decreased by 2% , then the number of beats heard per second will be

A sonometer wire is resonating with a tuning fork of frequency N. If its length is increased by 10% , by keeping the tension constant , 6 beats are heard per second, then

A tuning fork of frequency 200Hz is in unison with a sonometer wire. How many beats // sec will be heard if tension in the wire is increased by 2% ?

In an experiment with sonometer, a tuning fork of frequency 256 Hz resonates with a length of 25 cm and another tuning fork resonates with a length of 16 cm. Tension of the string remaining constant, the frequency of the second tuning fork is –

In an experiment with sonometer, a tuning fork of frequency 256 Hz resonates with a length of 25 cm and another tuning fork resonates with a length of 16 cm. Tension of the string remaining constant, the frequency of the second tuning fork is –

In an experiment with sonometer a tuning fork of frequency 256 Hz resonates with a length of 25 em and another tuning fork resonates with a length of 16 cm. Tension of the string remaining constant the frequency of the second tuning fork

In an experiment with sonometer a tuning frok of frequency 256 Hz reaonates with a length of 25 cm and another tuning frok resonates with a length of 16 cm. Tension of the string remaining counstant the frequency to the second tuning fork is

A stretched sonometer wire is in unison with a tuning fork. When the length of the wire is decreased by 1% 6 beats/s are heard, then the frequency of the tuning fork is

A sonometer wire of length 65cm is in resonance with a tuning fork of frequency N. If the length of the wire is decreased by 1cm and it is vibrated with the same tuning fork, 8 beats/s are heard, then the frequency of the tuning fork will be
