Problem

A satellite of mass 2.0×1042.0\times10^{4}\,kg is in circular orbit at a distance of 2RE2R_E from Earth’s center, where RER_E is Earth’s radius. The local gravitational acceleration on the satellite is measured to be 2.5\,m/s2^2. Taking Earth’s mass as 6.0×10246.0\times10^{24}\,kg, what is the magnitude of Earth’s simultaneous acceleration toward the satellite? (a) 3.3×10−20 m/s23.3\times10^{-20}\,\text{m/s}^2 (b) 2.1×10−21 m/s22.1\times10^{-21}\,\text{m/s}^2 (c) 8.3×10−21 m/s28.3\times10^{-21}\,\text{m/s}^2 (d) 1.2×10−19 m/s21.2\times10^{-19}\,\text{m/s}^2
