A) 250
B) 252
C) 260
D) 262
Correct Answer: B
Solution :
nA = Known frequency = 256 Hz, nB = ? x = 4 bps, which is decreasing after loading (i.e. x¯) also known tuning fork is loaded so nA¯ Hence nA¯ ? nB = x¯ ... (i) Correct nB ? nA¯ = x¯ ... (ii) Wrong Þ nB = nA ? x = 256 ? 4 = 252 Hz.You need to login to perform this action.
