Question

Two oscillators are started simultaneously in same phase. After 50 oscillations of one, they get out of phase by π. The half oscillation. The percentage difference of frequencies of the two oscillators is nearest to:

• A. 2%
• B. 1%
• C. 0.5%
• D. 0.25%

Hint:

Phase difference directly relates to difference in frequencies.

Answer 1

The Correct Option is B

Step 1: Phase difference π corresponds to half oscillation.
Step 2: Difference in oscillations after 50 cycles: Δ n = (1)/(2) ⟹ (Δ f)/(f) = (1)/(100)
Step 3: %difference = 1%
