. If two tuning forks A and B are sounded together
they produce 4 beats per second. A is then slightly loaded with wax,
they produce 2 beats when sounded again. The frequency of A is 256. The frequency of B will be
A: 250
B: 252
C: 260
D: 262
Best Answer
Explanation:
From the given,
When the tuning forks A and B are sounded together, 4 beats are produced per second.
That is,
256Hz-v=±4Hz
Now finding the frequency of B,
256Hz-v4Hz
⇒v=252Hz
Final answer:
Hence, option B is correct, i.e., 252.
