← ScienceWhich electrical field disruption occurs when a charged high-speed spacecraft excessively emits ions?
A)Wake contraction reduces capacitance
B)Plasma pinch halts ion emission
C)Space charge limits maximum flux✓
D)Magnetic damping reduces velocities
💡 Explanation
Space charge limits the emitted ion flux because the repulsive Coulomb force from previously emitted ions opposes further emission, therefore limiting current rather than causing pinch effects or reducing individual initial velocities.
