A tuning fork produces 2 beats per second when sounded with another tuning fork of frequency 250 Hz. It gives the same number of beats per second when loaded with wax. The initial frequency of `1^(st)` tuning fork is

A tuning fork of unknown frequency produces 4 beats per second when sounded with another tuning fork of frequency 254 Hz. It gives the same number of beats per second when unknown tuning fork loaded with wax . The unknown frequency before loading with wax is

A tuning fork of unknown frequency produces 4 beats per second when sounded with another tuning fork of frequency 254 Hz. It gives the same number of beats per second when unknown tuning fork loaded with wax . The unknown frequency before loading with wax is

A tuning fork A,marked 512 Hz, produces 5 beats per second,when sounded with another unmarked tuning fork B.If B is loaded with wax the number of beats is again 5 per second.What is the frequency of the tuning fork B when not loaded?

A tuning fork A, marked 512 Hz, produces 5 beats per second, when sounded with another unmarked tuning fork B. If B is loaded with wax, the number of beats is again 5 per second. What is the frequency of tuning fork B when not loaded?

A tuning fork A, marked 512 Hz, produces 5 beats per second, when sounded with another unmarked tuning fork B. If B is loaded with wax, the number of beats is again 5 per second. What is the frequency of tuning fork B when not loaded?

A tuning fork A produces 4 beats per second with another tuning fork B of frequency 320 Hz. On filing one of the prongs of A, 4 beats per second are again heard when sounded with the same fork B. Then the frequency of the fork A before filing is

A tuning fork A, marked 512 Hz, produces 5 beats per second, where sounded with another unmarked tuning fork B. If B is loaded with wax the number of beats is again 5 per second. What is the frequency of the tuning fork B when not loaded ?

A tuning fork produces 8 beats per second with a tuning fork D of frequency 350 Hz .When the prongs of fork C are loaded with wax, the number of beats heard is 10 per second. Find the original frequency of fork C.

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?
