A) \[\frac{1}{2}m{{v}^{2}}\,+\,\frac{1}{2}I{{\omega }^{2}}\]
B) \[\frac{1}{2}m{{v}^{2}}\,-\,\frac{G{{m}_{1}}{{m}_{2}}}{R}\]
C) \[\frac{1}{2}m{{v}^{2}}\,-\,\frac{1}{2}\,m{{R}^{2}}{{\omega }^{2}}\]
D) None of these
Correct Answer: A
Solution :
Total kinetic energy = Linear kinetic energy + rotational kinetic energy \[=\frac{1}{2}m{{v}^{2}}+\frac{1}{2}I{{\omega }^{2}}\]
