A charged particle is any object that has gained or lost electrons. Positively charged particles and negatively charged particles are the two primary forms of charged particles. Cations are positively charged particles, whereas anions are negatively charged particles. Objects like paper, comb, and straw can attract other objects while rubbing. Rubbing can change the properties of these objects and turn them into charged objects having charged particles, which attracts other particles. Let’s look at a basic task to see how this works. Just take a piece of paper and cut it into small pieces. Now iron them and put them in front of the TV or monitor screen. You will notice that these ironed pieces of paper are attracted to the monitor or TV screen for a while. This little activity proves that some particles can be activated into charged particles. To understand the outcome of charged particles in an electric field, we have to understand the concept and assumptions.
Charged particles have unique properties that make them exciting objects to study. They can be used to create smaller, more efficient, and more powerful devices than those created using uncharged particles. These five properties provide a basic understanding of charged particles and their behaviour.
Charge Density – The charge density of a charged particle is the number of charges per unit volume.
Electric Field – The electric field is a force that attracts charges towards each other. It is measured in units of volts per metre (V/m).
Magnetism – Magnetism is the ability of charged particles to attract and repel each other. It is measured in units of magnetism (A/m).
Circular Motion – The particles move around a centre point in a circular motion, much like a spinning top. The force of an electric field causes this motion.
Stability: The stability of charged particles is due to their collective behaviour. The particles will remain together in a stable configuration as long as the electric field persists.
All these above properties are essential to note when studying charge behaviour in an electric field.
There are some examples by which you can easily understand the concept of charged particles in EF (Electric field) –
When you have a charged particle moving in an electric field, the force is always in the direction of the electric field. This is why if you hold a metal object up to an electric wire, the metal will get pushed towards the positive end of the wire. This is because the electric field pushes the charged particles in the metal towards the positive end of the wire.
Every charged particle as well as charged item, receives a force in an electric field. If that force is in non-balance form, it will create movement in the object and start moving in an electric field.
There are implications that you need to note:
When placed in the electric field, the charged particle always feels the force, and it doesn’t matter that charged particles are in a moving state or in a resting state. The force can be denoted by –
F = qE
Where,
F = force acting on the charged particle,
q = charges on the particles, or you can say charged particles
E = electric field
Anyone can quickly identify the direction of force by looking at the charge value. If the particle is positively charged, then the acting force is parallel to the electric field. If the molecule is negatively charged, the acted force is inverse to the electric field[2].
For positively charged particles, F = EF (Force direction is parallel)
For negatively charged particles, F = EF (Force direction is opposite to the field)
The study of charged particles in an electric field can be pretty exciting. Positively charged particles and negatively charged particles are the two primary forms of charged particles. Cations are positively charged particles, whereas anions are negatively charged particles. A charged particle in an electric field will experience various effects depending on the charge and location. Additionally, the effects of a charged particle in the electric field greatly depend on the surrounding electric field. Electric fields are essential in many aspects of physics as they can be used to create force, attract electrons, and more.
