A) \[\sqrt{gR}\left( \sqrt{2}-1 \right)\]
B) \[\sqrt{2gR}\]
C) \[\sqrt{gR}\]
D) \[\sqrt{gR/2}\]
Correct Answer: A
Solution :
\[{{V}_{0}}=\sqrt{\frac{GM}{R}}\]or\[\sqrt{gR}\] \[{{V}_{e}}\sqrt{\frac{2GM}{R}}\]or\[\sqrt{2gR}\] \[\therefore \]Increase in velocity \[=\sqrt{gR}\left[ \sqrt{2}-1 \right]\]You need to login to perform this action.
