question

When two tuning forks are sounded simultaneously, a beat note of 5 cycles per second is heard. If one of the forks has a known frequency of 256 cycles per second, and if a small piece of adhesive tape fastened to this fork reduces the beat note to 3 cycles per second, what is the frequency of the other fork?
