A wire of length ' L ' and linear density ' m ' is stretched between two rigid supports with tension ' T '. It is observed that wire resonates in the P ^ th harmonic at a frequency of 320 Hz and resonates again at next higher frequency of 400 Hz . The value of ' p ' is

Options

  1. A2
  2. B4
  3. C8
  4. D10

Correct answer

B. 4

Step-by-step solution

aligned & 320= p 2 l ~F and 400= p +1 2 l ~F & 400 320 = p +1 p 400 p =320 p +320 & p =4 aligned
