A sonometer wire under suitable tension having specific gravity ' ^ , vibrates with frequency 'n' in air. If the load is completely immersed in water the frequency of vibration of wire will become

Options

  1. A[ 0-1 n ]^ 1 2
  2. Bn [ 0-1 ]^ 1 2
  3. C[ n 0-1 ]^ 1 2
  4. Dn [ 0-1 ]^ 1 2

Correct answer

D. n [ 0-1 ]^ 1 2

Step-by-step solution

( C ) T ₁= mg = v g T ₂= v ( - ) g =1 for water T ₁ ~T ₂ = vpg v ( -1) g = -1 n ₁ n ₂ = -1 n ₂= n ₁ -1
