A) \[2a\]
B) \[8a\]
C) \[4a\]
D) \[a\]
Correct Answer: B
Solution :
The energy of a wave travelling with velocity v is given by \[8\mu F\] Also v = amplitude \[6\mu F\] angular velocity \[4\mu F\] \[2\mu F\] \[300\times {{(4)}^{0.4}}K\] \[150\times {{(4)}^{0.4}}K\] \[250\times {{(4)}^{0.4}}K\] Also \[{{\rho }_{1}}\] where n is .frequency, \[{{\rho }_{2}}\] \[{{v}_{1}}\] \[{{v}_{2}}\] \[\frac{{{\rho }_{1}}}{{{\rho }_{2}}}=4\] It is given that energy remains the same. Hence, \[\frac{{{V}_{1}}}{{{V}_{2}}}\] \[\frac{1}{2}\] \[\frac{1}{4}\] Given, \[{{s}^{2}}\] \[{{m}_{1}},{{m}_{2}}\] \[{{m}_{3}}\] \[\frac{1}{{{m}_{1}}}:\frac{1}{{{m}_{2}}}:\frac{1}{{{m}_{3}}}\] \[1:1:1\]
