MHT CET 2025 Physics question
Two identical straight wires are stretched so as to produce 6 beats per second when vibrating simultaneously with tensions 'T' and 'T' respectively. On changing the tension slightly in one of them, the beat frequency remains unchanged. This will happen when (Given T > T)
Answer: (D)
Solution
For identical wires the frequency is . Since , and the beat frequency is Hz. Raising or lowering (options A, B, C) widens the gap , so the beats per second would increase above 6; they cannot stay at 6. The beat frequency can
