A) \[\frac{3}{4}\]
B) \[\frac{4}{3}\]
C) \[\frac{16}{9}\]
D) \[\frac{9}{16}\]
Correct Answer: D
Solution :
\[{{T}_{1}}=3=\sqrt[2\pi ]{\frac{m}{k}}\] Then, \[{{T}_{2}}=5=\sqrt[2\pi ]{\frac{m+1}{k}}\] Dividing, \[\frac{3}{5}=\sqrt{\frac{m}{m+1}}\] \[\frac{9}{25}=\frac{m}{m+1}\] \[9m+9=25m\] 16m=9 \[m=\frac{9}{16}\]You need to login to perform this action.
