In This post you will get answer of Q.
Two tuning forks A and B produce 4 beats/sec. Forks B and C produce 5 beats/sec. Forks A and C may produce ……. beats/sec
Solution:
We consider two possible cases about tuning forks $A, B$ and $C $
Case I When $A$ and $B$ are tuned, four beats are produced. When $B$ and $C$ are tuned, five beats are produced.
So, there is a difference of 1
$left|n_{A}-n_{C}right|=1$
Case II When $A$ and $C$ are tuned, the total number of beat produced.
$left|n_{C}-n_{A}right|=4+5=9$
