A tuning fork of known frequency 256 Hz makes 5 beats per second with the vibreting string of a piano.The beat frequency decreases to 2 beats per second when the tension in the piano string is slightly increased.The frequency of the piano string before increasing the tension was

A tuning fork of frequency 512 Hz makes 4 beats//s with the vibrating string of a piano. The beat frequency decreases to 2 beats//s when the tension in the piano string is slightly increased.The frequency of the piano string before increasing the tension was

A tuning fork of frequency 512 Hz makes 4 beats//s with the vibrating string of a piano. The beat frequency decreases to 2 beats//s when the tension in the piano string is slightly increased.The frequency of the piano string before increasing the tension was

A tuning fork of frequency 256 Hz gives 5 beats $/$s with a vibrating string of a piano. The beat frequency decreases to 2, when tension in the string is slightly increased. What was the frequency of the piano string before increasing the tension ?

A tuning fork of frequency 512 $Hz$ is vibrated with a sonometer wire and 6 beats per second are heard. The beat frequency reduces if the tension is the string is slightly increased . The original frequency of vibration of the string is

A tuning fork of frequency 512 Hz is vibrated with sonometer wire and 6 beats per seconds are heard. The beat frequency reduces if the tension in the string is slightly increased. The original freqency of vibration of the string is

A tuning fork of unknown frequency makes 4.00 beats per second with a standard fork of frequency 384 Hz. The beat frequency decreases when a small piece of wax is put on a prong of the first fork. What is the frequency of this fork?

A tuning fork is frequency 512Hz is vibrated with a sonometer wire and 6 beats per second are heard. The beat frequency reduces if the tension in the string of slightly increased. The original frequency of vibration of the string is

A tuning fork of frequency 280 Hz produces 10 beats per see when sounded with a vibrating sonometer string. When the tension in the string increases slightly, it produces 11 beats per see. The original frequency of the vibrating sonometer string is :

A tuning fork of frequency 256 Hz is producing 5 beats/sec with the vibrating string of a sitar. On increasing the tension in the string, the beat frequency becomes 3 beats/sec. The initial frequency of sitar before increasing the tension is

A tuning fork of frequency 512 Hz produces 6 beats per sec. with vibrating string of an instrument. On increasing the tension in the string, the beat frequency reduces to 3 beats/sec. Find the original frequency of the instrument.
