If R is the radius of orbit of a satellite, then the kinetic energy of the satellite is

Options

  1. A1 R
  2. B1 R
  3. CR
  4. D1 R^ 3 / 2

Correct answer

A. 1 R

Step-by-step solution

We know that, the kinetic energy of satellite revolving around a planet of radius of orbit R is KE = G M m 2 R where, M= mass of planet, m= mass of satellite R= radius of orbit G= universal gravitational constant. KE 1 R Hence, KE is inversely proportional to radius of orbit.
