A) \[0.\text{49m}/{{\text{s}}^{\text{2}}}\]
B) \[\text{9}.\text{8m}/{{\text{s}}^{\text{2}}}\]
C) \[\text{1}.\text{6 m}/{{\text{s}}^{\text{2}}}\]
D) \[0.\text{8m}/{{\text{s}}^{\text{2}}}\]
Correct Answer: A
Solution :
Earth | Planet |
\[{{M}_{1}}=80M\] | \[{{M}_{2}}=M\] |
\[{{D}_{1}}=2D\]\[\Rightarrow \] \[{{R}_{1}}=2R\] | \[{{D}_{2}}=D\]\[\Rightarrow \] \[{{R}_{2}}=R\] |
\[{{g}_{1}}=g=9.8m/{{s}^{2}}\] | \[{{g}_{2}}=?\] |
