A) R/2
B) R/3
C) R/5
D) R/4
Correct Answer: B
Solution :
\[u={{\upsilon }_{e}}/2,{{\upsilon }_{e}}=\]escape velocity of body for that planet \[{{h}_{\max }}=\frac{{{u}^{2}}}{{{2}_{g}}}R=\] radius of planet \[=\frac{\upsilon _{e}^{2}}{u\times 2g}\]g= acceleration due to gravity at that planet. \[=\frac{2Rg}{u\times 2g}{{\upsilon }_{e}}=\sqrt{2Rg}\] \[{{h}_{\max }}=R/4\]You need to login to perform this action.
