Two identical straight wires are stretched so as to produce ` 6 beats//s` when vibrating simultaneously . On changing the tension slightly in one of them , the beats frequency remains unchanged . If `T_(1) and T_(2)` are initial tensions in strings such that `T_(1) gt T_(2)` then it may be said while making above changes in tension :A. `T_(2)` was decreasedB. `T_(1)` was increasedC. both `T_(1) and T_(2)` were increasedD. either `T_(2)` was increased or `T_(1)` was decreased |
