A test charge is a small charge used to measure the electric field at a specific point. It is typically a positive charge with a known value. When placed in an electric field, the test charge experiences a force due to the field. By measuring this force, the strength and direction of the electric field at that point can be determined.

What is the relationship between the central charge and the electric field distribution within a spherical conductor with a cavity?
The central charge of a spherical conductor with a cavity affects the electric field distribution within the conductor. The electric field inside the conductor is zero, and the charge is distributed on the surface. The central charge influences how the charge is distributed on the surface, which in turn affects the electric field distribution within the conductor.
What is the relationship between the electric potential in a field and the work done in moving a charge within that field?
The electric potential in a field is directly related to the work done in moving a charge within that field. The electric potential represents the amount of work needed to move a unit positive charge from one point to another in the field. The work done in moving a charge within the field is equal to the product of the charge and the change in electric potential between the two points.
Which of the following is true about the electric field around an electric charge?
The electric field around an electric charge is a vector field that exerts a force on other charges placed in the field. The strength of the electric field decreases with distance from the charge following the inverse square law. The direction of the electric field is radially outward from a positive charge and radially inward toward a negative charge.
What factors determine the intensity of an electric field?
The intensity of an electric field is determined by the amount of charge creating the field and the distance from the charge. The closer you are to the charge, the stronger the electric field will be.
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 charge?
Charge is a physical property that causes matter to experience a force within an electromagnetic field.
A negatively charged object is placed within a positive electric field. what happens to the object?
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)

Is electric field dependent of magnitude of charge?
Yes, the electric field created by a point charge is directly proportional to the magnitude of the charge. As the charge increases, the electric field strength at a given distance from the charge also increases.
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.
Is the direction of the electric force on a charge is tangent to the field line?
No, the direction of the electric force on a charge is along the electric field vector and not necessarily tangent to the field line. The force on a charge will be in the same direction as the electric field if the charge is positive, and opposite if the charge is negative.
What is the trajectory of a charge in an electric field?
The trajectory of a charge in an electric field is determined by the direction and strength of the electric field. The charge will experience a force in the direction of the electric field, causing it to move along a path determined by the field's characteristics.
What is every electric charge surrounded by?
Every electric charge is surrounded by an electric field.
How can one determine the charge density from an electric field?
To determine the charge density from an electric field, you can use the formula: charge density electric field strength / (2 epsilon), where epsilon is the permittivity of the material. This formula relates the electric field strength to the charge density of the material.
