A) \[\frac{2}{7}\]
B) \[\frac{7}{2}\]
C) \[\frac{5}{7}\]
D) \[\frac{7}{5}\]
Correct Answer: C
Solution :
\[\frac{{{K}_{translational}}}{{{K}_{total}}}=\frac{\frac{1}{2}m{{v}^{2}}}{\frac{1}{2}I{{\omega }^{2}}+\frac{1}{2}m{{v}^{2}}}\] \[=\frac{\frac{1}{2}m{{v}^{2}}}{\frac{1}{2}.\frac{2}{5}m{{R}^{2}}{{\omega }^{2}}+\frac{1}{2}m{{v}^{2}}}=\frac{\frac{1}{2}}{\frac{7}{10}}=\frac{5}{7}\]
