Why E-Field exists between two oppositely charged plates and it is zero elsewhere?
The electric field (E-field) exists between two oppositely charged plates due to the distribution of electric charges on the plates. When one plate is positively charged and the other plate is negatively charged, an electric field is created between them.
The E-field is zero elsewhere because the region outside the plates does not have any charge distribution. In order for an electric field to be present, there must be a source of electric charge. When there is no charge distribution in the surrounding area, there is no electric field outside of the plates.
To summarize, the E-field exists between two oppositely charged plates because of the presence of electric charges on the plates. It is zero elsewhere because there is no charge distribution in those regions.
The existence of an electric field (E-field) between two oppositely charged plates is a result of the charges exerting forces on each other. This E-field is zero elsewhere because there are no charges present to create a force.
To better understand this concept, you can apply the principles of electrostatics. The E-field is a vector field that describes the force experienced by positive charges in the presence of electric charges. It is measured in volts per meter (V/m).
In the case of two oppositely charged plates, we have a positive charge on one plate and a negative charge on the other. According to Coulomb's law, these charges exert attractive forces on each other. The positive charges are drawn towards the negative charges, while the negative charges are drawn towards the positive charges.
The E-field is a representation of these forces. It points from the positive plate towards the negative plate, indicating the direction in which a positive test charge placed in the field would experience a force.
Now, why is the E-field zero elsewhere? This is because there are no charges present in the surrounding areas to create a force or influence the field. Without charges nearby, there are no forces being exerted, leading to an E-field of zero.
To summarize, the E-field exists between two oppositely charged plates because the charges on the plates generate forces that attract each other. The E-field is zero elsewhere because there are no charges nearby to create forces or influence the field.
