A) \[6\times {{10}^{19}}N\]
B) \[18\times {{10}^{25}}N\]
C) \[36\times {{10}^{21}}N\]
D) \[27\times {{10}^{39}}N\]
Correct Answer: C
Solution :
Here: Mass of earth \[{{M}_{e}}=6\times {{10}^{24}}kg\] Angular velocity of earth \[\omega =2\times {{10}^{-7}}rad\text{/}s\] Radius of circular orbit \[R=1.5\times {{10}^{8}}km\] \[=1.5\times {{10}^{11}}m\] Force exerted on the earth by the sun is given by \[F={{M}_{e}}R{{\omega }^{2}}\] \[=6\times {{10}^{24}}\times 1.5\times {{10}^{11}}\times {{(2\times {{10}^{-7}})}^{2}}\] \[=36\times {{10}^{21}}N\]
