Two satellites, A and B, have masses m and $\displaystyle 2$ m respectively. A is in a circular orbit of radius $\displaystyle R$, and $\displaystyle B$ is in a circular orbit of radius 2R around the earth. The ratio of their kinetic energies, $\displaystyle \mathrm{T}_{\mathrm{A}} / \mathrm{T}_{\mathrm{B}}$, is :
