A) 334
B) 339
C) 343
D) 347
Correct Answer: D
Solution :
nA = Known frequency = 341 Hz, nB =? x = 6 bps, which is decreasing (i.e. x¯) after loading (from 6 to 1 bps) Unknown tuning fork is loaded so nB¯ Hence nA ? nB¯ = x¯ ... (i) Wrong nB¯ ? nA = x¯ ... (ii) Correct Þ nB = nA + x = 341 + 6 = 347 Hz.You need to login to perform this action.
