JEE AdvancedPhysicsWavesNumerical+4 / −1
A string of length 1 m1 \mathrm{~m}1 m and mass 2×10−5 kg2 \times 10^{-5} \mathrm{~kg}2×10−5 kg is under tension TTT. When the string vibrates, two successive harmonics are found to occur at frequencies 750 Hz750 \mathrm{~Hz}750 Hz and 1000 Hz1000 \mathrm{~Hz}1000 Hz. The value of tension TTT is ‾\underline{\hspace{2cm}}​ Newton.
