A) 253 Hz
B) 262 Hz
C) 250 Hz
D) 259 Hz
Correct Answer: B
Solution :
nA = Known frequency = 256 Hz, nB = ? x = 6 bps, which remains the same after loading. Unknown tuning fork F2 is loaded so nB¯ Hence nA ? nB¯ = x ... (i) Wrong nB¯ ? nA = x ... (ii) Correct Þ nB = nA + x = 256 + 6 = 262 Hz.You need to login to perform this action.
