← ScienceWhich acceleration results from indistinguishable inertial/gravitational forces under Einstein's equivalence principle?
A)Spacetime curvature near massive objects✓
B)Velocity increase through electromagnetic radiation
C)Frame dragging near rotating bodies
D)Tidal flexing of planetary crusts
💡 Explanation
Einstein's equivalence principle states inertial forces are locally indistinguishable from gravitational, therefore acceleration mirrors spacetime curvature near masses rather than arising because of velocity increases. Tidal forces are gradients, not uniform, rather than fitting equivalence principle.
