The fundamental frequency of a plucked wire under a tension of 400N is 250Hz. When the frequency is changed to 500 Hz at constant length, the tension is By: Sunday|Published on: Nov 11|Categories: Physics JAMB| 0 comments A. 1600N B. 400N C. 160N D. 40N Correct Answer: Option A = 1600N Users Also Read These:A string under tension produces a note of frequency…A wire of length 400cm is stretched between two…A wire of length 100.0m at 30° has linear expansive…As the air column of length L in an air pipe…If a sonometer has a fundamental frequency of 450HZ;…SEE ALSO A string of length 1.0 m vibrates in 10 loops.
