A) 250 Hz
B) 253 Hz
C) 259 Hz
D) 262 Hz
Correct Answer: C
Solution :
It is given that nA = Unknown frequency = ? nB = Known frequency = 256 Hz x = 3 bps, which remains same after loading Unknown tuning fork A is loaded so nA¯ Hence nA¯ ? nB = x ... (i) Correct nB ? nA¯ = x ... (ii) Wrong Þ nA = nB + x = 256 + 3 = 259 Hz.You need to login to perform this action.
