$A$ satellite of mass $m$ rotates around the Earth in a circular orbit of radius $R$. If the angular momentum of the satellite is $J$,then its kinetic energy $(K)$ and the total energy $(E)$ of the satellite are:

• A
  $K=\frac{J^2}{m R^2}, E=-\frac{J^2}{2 m R^2}$
• B
  $K=\frac{J^2}{2 m R^2}, E=-\frac{J^2}{2 m R^2}$
• C
  $K=\frac{J^2}{2 m R^2}, E=-\frac{J^2}{m R^2}$
• D
  $K=\frac{J^2}{2 m R^2}, E=\frac{J^2}{m R^2}$
