A satellite orbits Earth at a distance of 2R from Earth's center (R = Earth's radius). If the gravitational field at Earth's surface is g, what is the gravitational field at the satellite's position?
A.g/2
B.g/4
C.2g
D.4g
Explanation
Core Concept
Gravitational field follows an inverse square law: g ∝ 1/r². At 2R, the field is g/(2²) = g/4.
Correct Answer
Bg/4
