All Flashcards
What is the effect of increasing the charge of an object on the electric field strength?
The electric field strength increases.
What happens to the gravitational field strength as you move farther away from a massive object?
The gravitational field strength decreases.
What is the effect of increasing the distance between two charges on the electric force between them?
The electric force decreases.
What is the effect of the motion of electric charges?
Creates a magnetic field.
What happens to the electric field when two equal positive charges are placed on the x-axis?
The electric field is zero at the midpoint between them.
What are the key differences between monopole and dipole fields?
Monopole: Single source, strength decreases with distance. Dipole: Two sources, more complex behavior, strength decreases with distance.
Compare the electric field due to a point charge and the gravitational field of a spherical mass.
Both are monopole fields. Electric field strength is proportional to charge; gravitational field strength is proportional to mass. Both are inversely proportional to the square of the distance.
Contrast the electric field on the x-axis versus the y-axis for two equal and opposite charges (+q and -q) placed at ±d from the origin.
x-axis: Net electric field is non-zero. y-axis: Net electric field is zero.
Compare the strength of an electric dipole field between the charges and far away from the charges.
Strongest between the charges and decreases as you move away.
Compare the net electric field of a dipole on the x-axis versus the y-axis.
x-axis: non-zero, y-axis: zero
What is a monopole field?
A field that originates from a single source and decreases in strength with distance.
What is a dipole field?
A field created by two distinct sources (e.g., north and south poles).
What is a point charge model?
Treating a charged object as a point charge if its size is small compared to the distances involved.
Define electric dipole field.
A field created by two equal and opposite charges separated by a distance.
Define magnetic field.
A field created by the motion of electric charges (current-carrying wires, moving charged particles).
