A) \[4.9\,m/{{s}^{2}}\]
B) \[0.98\,m/{{s}^{2}}\]
C) \[0.49\,m/{{s}^{2}}\]
D) \[49\,m/{{s}^{2}}\]
Correct Answer: C
Solution :
\[{{g}_{p}}={{g}_{e}}\,\left( \frac{{{M}_{p}}}{{{M}_{e}}} \right)\,{{\left( \frac{{{R}_{e}}}{{{R}_{p}}} \right)}^{2}}=9.8\,\left( \frac{1}{80} \right)\,{{(2)}^{2}}\] \[=9.8/20=0.49\,\,m/{{s}^{2}}\]You need to login to perform this action.
