A) \[2\pi \times {{10}^{5}}\,rad/s\]
B) \[\pi \times {{10}^{5}}\,rad/s\]
C) \[\frac{5\pi }{3}\times {{10}^{5}}\,rad/s\]
D) \[\frac{5\pi }{2}\times {{10}^{5}}\,rad/s\]
Correct Answer: B
Solution :
[b] \[\frac{V}{{{V}_{0}}}={{10}^{-12}}\Rightarrow \frac{\frac{4}{3}\pi {{r}^{3}}}{\frac{4}{3}\pi {{R}^{3}}}={{10}^{-12}}\Rightarrow \frac{r}{R}={{10}^{-4}}\] Angular momentum conservation givesYou need to login to perform this action.
