A) \[6:7\]
B) \[36:49\]
C) \[7:6\]
D) \[343:216\]
Correct Answer: A
Solution :
From the relation, \[\overline{KE}=\frac{3}{2}KT\] \[\Rightarrow \] \[\frac{{{(\overline{KE})}_{1}}}{{{(\overline{KE})}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\] (become\[k\]is constant) Given, \[{{T}_{1}}=300\,\,K,\,\,{{T}_{2}}=350\,\,K\] \[\therefore \] \[\frac{{{(KE)}_{1}}}{{{(KE)}_{2}}}=\frac{300}{350}=\frac{6}{7}\]
