Answer» B go around planet P in circular orbits of radii 4 R and R respectively.velocity of a SATELLITE = vmass of a satellite = MMASS of planet = Mradius of ORBIT = Rcentripetal FORCE = m v² / R = G M m / R² => v² = G M / R velocity of a satellite is inversely proportional to the radius of the orbit. v_B² / v_A² = R_A / R_B v_B² = 4 R / R * (3 V)² = 36 V² v_B = velocity of satellite B = 6 V, twice the velocity of satellite A. |
