A certain fork is found to give ` 2 beats//s` when sounded in conjuction with a stretched string vibrating transversely under a tension of either `10.2 or 9.9 kg weight`. Calculate the frequency of fork.

A tuning fork is found to give 20 beats "in" 12 s when sounded in conjuction with a stretched string vibrating under a tension of 10.2 or 9.9 kgf . Calculate the frequency of the fork.

A tuning fork is found to give 20 beats in 12 seconds when sounded in conjuction with a stretched string vibrating under a tension of 10.2 or 9.9 kgf. Calculate frequency of the fork

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 A of frequency 512 Hz sounded with another tuning fork B gives 5 beats/sec. On loading B with a piece of wax, and on sounding, again 5 beats/sec are produced. Calculate the frequency of fork B.

When two tuning forks were sounded together , 20 beats were produced in 10 seconds. On loading one of the fork with wax, the number of beats increases. If the frequency of unloaded fork is 512Hz , calculate the frequency of other.

A tuning fork A frequency 384Hz gives 6 beats in 2 seconds when sounded with another tuning fork B. What could be the frequency of B?

A tuning fork A frequency 384Hz gives 6 beats in 2 seconds when sounded with another tuning fork B. What could be the frequency of B?

A tuning fork A frequency 384Hz gives 6 beats in 2 seconds when sounded with another tuning fork B. What could be the frequency of B?

Two tuning forks A and B give 4 beats/s when sounded together. If the fork B is loaded with wax 6 beats/s are heard. If the frequency of fork A is 320 Hz, then the natural frequency of the tuning fork B will be

A fork of unknown frequency gives 4 beats per second when sounded with another of frequency 256 . The fork is now loaded with a piece of wax and again 4 beats per second are heard. Calculate the frequency of the unknown fork.
