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
264
B
263
C
256
D
260
Text Solution
Verified by Experts
The correct Answer is:
C
When tuning frok A is loded with wax, then its frequency decreaces `therefore" "f_(A) - f_(B)=4therefore260-f_(B)=4` `therefore" "f_(B)=256 Hz`
