A) 270, 280
B) 260, 270
C) 260, 250
D) 260, 280
Correct Answer: C
Solution :
\[{{n}_{1}}-{{n}_{2}}=10\] ..?(i) Using \[{{n}_{1}},=\frac{v}{4{{l}_{1}}}\] and \[{{n}_{2}}=\frac{v}{4{{l}_{2}}}\] Þ \[\frac{{{n}_{1}}}{{{n}_{2}}}=\frac{{{l}_{2}}}{{{l}_{1}}}=\frac{26}{25}\] ?..(ii) After solving these equation \[{{n}_{1}}=260Hz\],\[{{n}_{2}}=250\]\[Hz\]You need to login to perform this action.
