Two idential straight wires are stretched so as to produce `6` beats per second when vibrating simultaneously. On changing the tension slightly in one of them, the beat frequency remains unchanged. Denoting by `T_(1)`, `T_(2)` the higher and the lower initial tension in the strings, then it could be said that while making the above changes in tension,

A

`T_(2)` was decreased

B

`T_(2)` was increased

C

`T_(1)` was increased

D

`T_(1)` was decreased

Two identical straight wires are stretched so as to products 6 beats// s when vibrating simultaneously. On changing the tension slightly in one of them, the beat frequency remains unchanged. Denoting by T_(2) , T_(2) the higher and the lower initial tension in the strings, then it could be said that that while making the above changes in tension (a) T_(2) was decreased (b) T_(2) was decreased (c) T_(1) was decreased (d) T_(1) was decreased

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 :

Two wires are stretched under tension of T_(1) and T_(2) such that T_(2) gt T_(1) , producing 4 beats per seconds on vibrating. When the tension in one of them is changed slightly even then the beat frequency remains 4. Which of the two T_(1) or T_(2) should be increased or decreased ?

Wire having tension 225 N produces six beats per second when it is tuned with a fork. When tension changes to 256 N, it is tuned with the same fork, the number of beats remain unchanged. The frequency of the fork will be

A tuning fork of known frequency 256 Hz makes 5 beats per second with the vibrating string of a piano. The beat frequency decreases to 2 beats per second when the tension in the piano string is slightly increased. The frequency of the piano string before increasing the tension was

A vibrating string produces 2 beats per secod when sounded with a turning fork of frequency 256Hz . Slightly increasing the tension in the string produces 3 beats per second. The initial frequency of the string may have been

A tuning fork of frequency 280 Hz produces 10 beats per see when sounded with a vibrating sonometer string. When the tension in the string increases slightly, it produces 11 beats per see. The original frequency of the vibrating sonometer string is :

Two strings X and Y of a sitar produce a beat frequency 4 Hz.When the tension of the string Y is slightly increased the beat frequency is found to be 2 Hz. If the frequency of X is 300 Hz,then the original frequency of Y was

A piano wire A vibrates at a fundamental frequency of 600 Hz. A second identical wire B produces 6 beats per second with it when the tension in A is slightly increased. Find the ratio of the tension in A to the tension in B.
