A) \[\frac{v(n-1)}{n}\]
B) \[\frac{v(n+1)}{n}\]
C) \[\frac{v(n+1)}{n}\]
D) None of these
Correct Answer: B
Solution :
\[0.81\] or \[0.42\] or \[{{r}_{A}}\] ??..(i) Applying conservation of energy \[{{r}_{B}}\] \[{{v}_{A}}\] ??..(ii) Solving Eqs. (i) and (ii), we get \[{{v}_{B}}\] From Eq. (i) \[\frac{{{v}_{A}}}{{{v}_{B}}}\] \[\frac{{{r}_{B}}}{{{r}_{A}}}\] \[\frac{{{r}_{A}}}{{{r}_{B}}}\]
