A satellite moves around the earth in a circular orbit with speed `v`. If `m` is the mass of the satellite, its total energy isA. `1/2 mv^(2)`B. `1/4 mv^(2)`C. `-1/4 mv^(2)`D. `-1/2 mv^(2)` |
|
Answer» Correct Answer - D `therefore` Total energy of the satellite is `E=-1/2 (GM_(e)m)/(R_(e))` where `k=1/2(GMM_(e)m)/(R_(e))` `therefore` Total energy =-kinetic energy `E=-1/2 mv^(2)` putting the value of KE in the form of mass of a satellite m and speed v |
