A) 502
B) 507
C) 517
D) 522
Correct Answer: C
Solution :
After filling frequency increases, so \[{{n}_{A}}\] decreases (¯). Also it is given that beat frequency increases (i.e., x ) Hence nA¯ ? nB = x ... (i) Correct nB ? nA = x ... (ii) Wrong Þ nA = nB + x = 512 + 5 = 517 Hz.You need to login to perform this action.
