A) about \[9.8\times {{10}^{6}}\,J\]
B) about \[6.4\times {{10}^{8}}\,J\]
C) about \[3.1\times {{10}^{10}}\,J\]
D) about \[27.4\times {{10}^{12}}\,J\]
Correct Answer: C
Solution :
Given\[m=500\,\,kg,\,\,g=9.8\,\,m/{{s}^{2}}\] AND\[{{R}_{e}}=6.4\times {{10}^{6}}m\] Energy required to scape \[E=mg\,\,{{R}_{e}}\] \[=500\times 9.8\times 6.4\times {{10}^{6}}\] \[=3.1\times {{10}^{10}}J\]
