When electric flux is zero then electric field is also zero why?
The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
Is electric field strength scalar or vector?
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.
When is it valid to approximate a charge distribution by a point charge?
A charge distribution can be approximated as a point charge when the distance from the charge to the point of interest is much larger than the size of the charge distribution itself. This is often valid when the charge distribution is symmetric and the point of interest is located far away, allowing the electric field to be treated as originating from a single point. Additionally, if the total charge of the distribution is known, it can simplify calculations in electrostatics.
What is dimensional formula of coulomb?
The Coulomb is a unit of electric charge. [Charge] is a fundamental quantity.
What is the Charge dimensional formula?
The dimensional formula for electric charge is expressed as ([A \cdot T]), where (A) represents the unit of electric current (amperes) and (T) represents time (seconds). This indicates that charge can be derived from the flow of electric current over time. In the SI system, the unit of charge is the coulomb, which is equivalent to one ampere-second.
Something that surrounds every electric charge?
An electric field.
What is the area that surrounds an electric charged called?
The area that surrounds an electric charge is called an electric field. It exerts a force on other charged objects in the vicinity, either attracting or repelling them depending on their charge.
An electric field surrounds an electric charge What additional field surrounds a moving electric charge?
A moving electric charge produces both an electric field and a magnetic field. The magnetic field surrounds the moving charge and is perpendicular to both the direction of motion and the electric field. This combined electromagnetic field is described by Maxwell's equations.
Which type if field is present near a moving electric charge?
An electric field is present near a moving electric charge. The electric field is a force field that surrounds an electric charge and exerts a force on other charges in its vicinity.
What is the behavior of the electric field outside a sphere?
The behavior of the electric field outside a sphere is that it behaves as if all the charge of the sphere is concentrated at its center. This means that the electric field outside the sphere follows the same pattern as if the entire charge of the sphere was located at its center.
What is the electric field of a uniformly charged sphere?
The electric field of a uniformly charged sphere is the same as that of a point charge located at the center of the sphere. This means that the electric field is radially outward from the center of the sphere and its magnitude decreases as you move away from the center.
What surrounds electric charge and exerts force on other charges?
Electric charges are surrounded by an electric field, which exerts a force on other charges. This force can either attract or repel depending on the charges involved and their distance from each other.
What surrounds electric charges and exerts force on other charges?
An electric field surrounds the charge and exerts force on other charges.
What is the electric field produced by a single point charge in vacuum?
The electric field produced by a single point charge in vacuum is a force field that surrounds the charge and exerts a force on other charged particles in the vicinity. The strength of the electric field decreases with distance from the charge and follows the inverse square law.
Explanation for rutheford's nuclear atom model?
Each atom has a charged center (nuclei) with the positive electric charge and electron(s) rotates around this center with the negative electric charge.
What surrounds all electric charges?
Electric charges are surrounded by an electric field, which is a region of space where other charges can experience a force. The strength of the electric field depends on the magnitude of the charge creating it and the distance from the charge. Electric fields play a fundamental role in understanding and analyzing the behavior of electric charges.
What is the electric field outside a charged spherical shell?
Outside a charged spherical shell, the electric field behaves as if all the charge is concentrated at the center of the shell. This is known as Gauss's Law for a spherical surface, which states that the electric field at a distance r from the center of a charged spherical shell is equivalent to that of a point charge with the same total charge as the shell at the center. Therefore, the electric field outside a charged spherical shell decreases with the square of the distance from the center of the shell.
