All Flashcards
What happens when like charges are brought near each other?
They repel each other.
What happens when opposite charges are brought near each other?
They attract each other.
What is the effect of increasing the distance between two charges?
The electrostatic force between them decreases (inversely proportional to the square of the distance).
What is the effect of increasing the charge magnitude on the electric field?
The electric field strength increases.
What happens when a charge is placed in an electric field?
The charge experiences a force:
What are the key differences between electric force and electric potential?
Electric Force: Vector quantity, measured in Newtons (N). Electric Potential: Scalar quantity, measured in Volts (V).
How does electric potential and electric field vary with distance from a point charge?
Electric Potential: Varies inversely with distance (1/r). Electric Field: Varies inversely with the square of the distance (1/r^2).
What are the differences between positive and negative charges?
Positive Charges: Electric field lines point away from positive charges. Negative Charges: Electric field lines point towards negative charges.
Compare and contrast Coulomb's Law and Gauss' Law.
Coulomb's Law: Calculates force between point charges, best for simple arrangements. Gauss' Law: Relates electric flux to enclosed charge, best for symmetric charge distributions.
What are the similarities between electric potential and electric potential energy?
Electric Potential: Potential energy per unit charge (V = U/q). Electric Potential Energy: Energy a charge has due to its location in an electric field (U = qV).
What happens when like charges are brought near each other?
They repel each other.
What happens when opposite charges are brought near each other?
They attract each other.
What is the effect of increasing the distance between two charges on the electrostatic force?
The electrostatic force decreases (inversely proportional to the square of the distance).
What happens to the electric field when moving from high to low potential?
Electric field lines point from regions of high potential to regions of low potential.
