Question 85

Two satellites, P P\,P and QQQ, orbit a planet of mass M M\,M in stable circular orbits. The mass of satellite P P\,P is three times the mass of satellite QQQ (mP=3mQm_P = 3m_QmP​=3mQ​), and the orbital radius of P P\,P is four times the orbital radius of QQQ (rP=4rQr_P = 4r_QrP​=4rQ​).

What is the ratio of the kinetic energy of P P\,P to the kinetic energy of QQQ, Ek,PEk,Q\displaystyle \frac{E_{k,P}}{E_{k,Q}}Ek,Q​Ek,P​​?
