Coulombs law (basic)

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the electrostatic force between two charged objects, stating that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

Front

What is the formula for Coulomb's Law?

Back

F = k * |q1 * q2| / r^2, where F is the force between the charges, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the centers of the two charges.

Front

What type of force exists between two protons?

Back

A repulsive force.

Front

What happens to the electrostatic force when the distance between two charges increases?

Back

The electrostatic force decreases.

Front

What is the relationship between distance and electrostatic force?

Back

The relationship is inversely proportional.

Front

When are electric forces strongest?

Back

Electric forces are strongest when charges are close together.

Front

What charge does an atom of oxygen have if it has 8 protons and 10 electrons?

Back

It is negatively charged because it has excess electrons.

Front

If the distance between two charges doubles, how does the force change?

Back

The force is reduced by 1/4.

Front

What is the effect of like charges on each other?

Back

Like charges repel each other.

Front

What is the effect of opposite charges on each other?

Back

Opposite charges attract each other.
