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 km`D. its period of rotation must be `gt2pisqrt(R//g)` where `R` is radius of earth |

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