For a satellite in an orbit around the earth, the ratio of kinetic energy to potential energy is:

Options

  1. A1 2
  2. B1 2
  3. C2
  4. D2

Correct answer

A. 1 2

Step-by-step solution

- GMm R^2 +m ^2 R=0 aligned GMm R^2 & =m ^2 R K.E. = 1 2 I ^2 & = 1 2 m R^2 ^2 & = GMm 2 R aligned aligned & P . E .=- GMm R K . E= |P E| 2 & K E P E = 1 2 aligned
