For a satellite to orbit around the earth, which of the following must be true?A. It must be above the equator at some timeB. It cannot pass over the poles at any timeC. Its height above the surface cannot exceed 36,000 kmD. Its period of rotation must be `gt 2pi sqrt(R//g)` where R is radius of earth |

Answer» Correct Answer - A::D `T= 2pi sqrt((r^(3))/(GM))` `T_(min)=2pi sqrt((R^(3))/(GM))` `T_(min)=2pi sqrt((R )/(g))` So choice (A) and (D) are correct choice. |
