A) \[\frac{d_{1}^{2}{{v}_{1}}}{d_{2}^{2}}\]
B) \[\frac{{{d}_{2}}{{v}_{1}}}{{{d}_{1}}}\]
C) \[\frac{{{d}_{1}}{{v}_{1}}}{{{d}_{2}}}\]
D) \[\frac{d_{2}^{2}{{v}_{1}}}{d_{1}^{2}}\]
Correct Answer: C
Solution :
Angular momentum remains constant \[m{{v}_{1}}{{d}_{1}}=m{{v}_{2}}{{d}_{2}}\,\Rightarrow \,{{v}_{2}}=\frac{{{v}_{1}}{{d}_{1}}}{{{d}_{2}}}\]You need to login to perform this action.
