A) 286 cps
B) 292 cps
C) 294 cps
D) 288 cps
Correct Answer: B
Solution :
nA = Known frequency = 288 cps, nB = ? x = 4 bps, which is decreasing (from 4 to 2) after loading i.e. x¯ Unknown fork is loaded so nB¯ Hence nA ? nB¯ = x¯ Wrong nB¯ ? nA¯ = x¯ Correct Þ nB = nA + x = 288 + 4 = 292 Hz.You need to login to perform this action.
