A) 64/27
B) 256/81
C) 4/3
D) 16/9
Correct Answer: B
Solution :
\[\lambda T=\]constant \[{{\lambda }_{0}}T=\frac{3{{\lambda }_{0}}}{4}{{T}_{1}}\] \[{{T}_{1}}=\frac{4}{3}T\] \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{T_{1}^{4}}{T_{2}^{4}}=\frac{{{T}^{4}}}{{{\left( \frac{4}{3}T \right)}^{4}}}\] \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{81}{256}\] \[{{E}_{2}}=\frac{256}{81}{{E}_{1}}\]You need to login to perform this action.
