A) \[1/2\]
B) \[\sqrt{{}}2\]
C) 2
D) 4
Correct Answer: C
Solution :
: \[{{g}_{e}}=\frac{G{{M}_{e}}}{R_{e}^{2}}\] \[{{g}_{P}}=\frac{G{{M}_{P}}}{R_{l}^{2}}\] \[\therefore \] \[\frac{{{g}_{e}}}{{{g}_{p}}}=\frac{{{M}_{e}}}{{{M}_{p}}}\times {{\left( \frac{{{R}_{p}}}{{{R}_{e}}} \right)}^{2}}=\frac{{{M}_{e}}}{2{{M}_{e}}}\times {{\left( \frac{2{{R}_{e}}}{{{R}_{e}}} \right)}^{2}}\] \[\therefore \] \[\frac{{{g}_{e}}}{{{g}_{p}}}=\frac{2}{1}\]You need to login to perform this action.
