COULOMB'S LAW

Charles-Augustin de Coulomb

_____________ __ _______ (1736–1806) described the force between two charges using a torsion balance. He discovered an inverse square relationship between the electrostatic force and the distance of separation of the charges

Coulomb’s Law

__________ ____ states that the magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Free-body diagrams

_______  ________ are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation

superposition of forces

In getting the net force on a point charge in a system of charges, _________ __ ______ should be applied

Coulomb’s law

In order to quantify the forces between two charges, _________ ___ is used.

directly

This law states that the magnitude of the electric force between two point charges is
______ proportional to the product of the two charges and inversely proportional to the
square of the distance between them.

two charges

This law states that the magnitude of the electric force between two point charges is
directly proportional to the product of the ___ ______ and inversely proportional to the
square of the distance between them.

square

This law states that the magnitude of the electric force between two point charges is
directly proportional to the product of the two charges and inversely proportional to the
______ of the distance between them.

Thus, if you double the distance separation,
the electrostatic force will decrease by one-fourth.

double

In order to quantify the forces between two charges, Coulomb’s law is used.
This law states that the magnitude of the electric force between two point charges is
directly proportional to the product of the two charges and inversely proportional to the
square of the distance between them.

Thus, if you ______ the distance separation,
the electrostatic force will decrease by one-fourth.

inverse-square

There is an ___________ relationship between electrostatic force and distance separation of forces.

repulsive

Two positive charges will have a/an _______ force.

not possible

If two charges are along the x-axis, it is (possible or not possible) for a third charge placed along their line of connection a net force along the y-axis.

charges

The direction of the electrostatic force is determined by the ______ of the particles.

stationary

Coulomb’s law assumes that charges which are interacting are _______.
