What would happen to a charge that is placed in an Electric Field = 0?

Click For Summary

Discussion Overview

The discussion centers on the effects experienced by a charge placed in a region where the electric field is equal to zero. Participants explore theoretical implications, conditions under which the charge is placed, and the influence of other forces such as gravity.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that a charge placed in a region with no electric field would remain stationary, implying no effect on the charge.
  • Others argue that if a charge is placed in a gravitational field but not in an electric field, it would accelerate due to gravity, potentially leading to electromagnetic radiation.
  • One participant questions the premise of placing a charge in a zero electric field, stating that electric fields are present everywhere and that a charge in such a field would not experience a force.
  • Another participant clarifies that a charge in a zero electric field would not experience any electric force, emphasizing the conditions of the placement.
  • It is proposed that moving a charge into a zero electric field would superimpose its own electrostatic field, affecting the region and potentially creating transient electromagnetic waves.
  • A later reply introduces the concept of relative motion, suggesting that if a charge accelerates towards another stationary charge, both would experience forces due to exchanged electromagnetic waves.

Areas of Agreement / Disagreement

Participants express differing views on the implications of placing a charge in a zero electric field, with no consensus reached on the effects or the nature of the electric field itself.

Contextual Notes

Some assumptions about the nature of electric fields and the conditions of placement remain unresolved, particularly regarding the definition of a zero electric field and the influence of other forces.

If a charge was placed inside an electric field, where the electric field was equal to zero, what effect would the charge have?
 
Physics news on Phys.org
If the particle with mass and charge is placed in a region with no electric field and no gravitational field, the particle would just stay where it is placed, ie. nothing would happen to the particle.

If the particle is placed in a region with a gravitational field but no electric field, the particle would accelerate due to the influence of gravity, which would cause the particle to radiate electromagnetic waves.

electric field has value everywhere every time.
usually placing a charge inside an electric field would mean moving it to some place at sime time where electric field is not 0. I do not not understand what you mean by placing a charge inside an electric field where the electric field is equal to zero.
electric field apllies no force to body that is in place where electric field is 0.

Do you mean placed in a region where the electric field is zero? It would experience no electric force.
 
It would superimpose its own electrostatic field on the zero field which would have otherwise been present.

The act of moving the charge to this position would, of course, have the effect of superimposing transient electromagnetic waves on the pre-existing zero field in the region.
 
Relative motion is a thing. If a charge accelerates towards a stationary charge, they will both experience a force due to that 'exchanged' EM wave.
