When a tuning fork `A` of frequency `100 Hz` is sounded with a tuning fork `B`, the number of beats per second is `2`. On putting some wax on the prongs of `B`, the number of beats per second becomes `1`. The frequency of the fork `B` is

A tuning fork A of frequency 200 Hz is sounded with fork B , the number of beats per second is 5. By putting some wax on A , the number of beats increases to 8. The frequency of fork B is

A tuning fork A of frequency 512 Hz produces 4 beats per second when sounded with a tuning frok B. Dut to filling of the prongs of the tuning for B, the number of the beats per second becomes 6. The actual frequenct of B is

When a tuning fork of frequency 341 is sounded with another tuning fork, six beats per second are heard. When the second tuning fork is loaded with wax and sounded with the first fork, the number of beats is two per second. The natural frequency of the second tuning fork is

When a tuning fork of frequency 341 is sounded with another tuning fork, six beats per second are heard. When the second tuning fork is loaded with wax and sounded with the first fork, the number of beats is two per second. The natural frequency of the second tuning fork is

When a tuning fork A of unknown frequency is sounded with another tuning fork B of frequency 256Hz, then 3 beats per second are observed. After that A is loaded with wax and sounded, the again 3 beats per second are observed. The frequency of the tuning fork A is

When a tuning fork A of unknown frequency is sounded with another tuning fork B of frequency 256Hz, then 3 beats per second are observed. After that A is loaded with wax and sounded, the again 3 beats per second are observed. The frequency of the tuning fork A is

A tuning foork A of frequenct 260 c/s Hz produces 4 beats per second when sounded with a tuning fork B. the number of beats produced per second becomes 3. Then, what is the frequency of tuning fork B?

A tuning fork A of frequency 384 Hz gives 6 beats per second when sounded with another tunig fork B.On loading B with a littile wax,the number of beats per second becomes 4.What is the frequency of B?

When a tuning fork A and B are sounded together,the number of beats heard are 4 per second.When tuning fork A is field,the number of beats heard per second with B is changed to 3.If the frequency of tuning fork B is 384 Hz,the original frequency of A is

When a tuning fork A and B are sounded together,the number of beats heard are 4 per second.When tuning fork A is field,the number of beats heard per second with B is changed to 3.If the frequency of tuning fork B is 384 Hz,the original frequency of A is
