Coulomb's Law and Electric Forces

What does Coulomb's Law describe?

• The relationship between mass and gravity.

• The mathematical relationship between two point charges, their distance, and the force between them.

• The behavior of magnetic poles.

• The speed of light in a vacuum.

What happens when two like charges are brought near each other?

• They attract each other.

• They repel each other.

• They neutralize each other.

• They have no effect on each other.

What happens when two opposite charges are brought near each other?

• They repel each other.

• They neutralize each other.

• They attract each other.

• They have no effect on each other.

In Coulomb's Law equation (F = k q1 q2 / r^2), what does 'F' represent?

• Frequency

• Friction

• Force of attraction/repulsion

• Field strength

In Coulomb's Law equation, what do 'q1' and 'q2' represent?

• Quantity of matter

• Charges of the point particles

• Quanta of energy

• Quality of interaction

In Coulomb's Law equation, what does 'r' represent?

• Radius of the particles

• Resistance

• Rate of reaction

• Distance between the two charges

How does decreasing the distance between two charged objects affect the force between them?

• The force becomes weaker.

• The force becomes stronger.

• The force remains unchanged.

• The force becomes zero.

If the distance between two charged objects is increased, what happens to the force of attraction or repulsion between them?

• It increases.

• It decreases.

• It remains the same.

• It becomes infinite.

How does increasing the magnitude of the charges on two objects affect the force between them?

• The force becomes weaker.

• The force becomes stronger.

• The force remains unchanged.

• The force becomes zero.

Why is Coulomb's Law important in chemistry?

• It explains the behavior of gases.

• It helps predict the behavior of charged particles in chemical reactions.

• It describes the properties of metals.

• It is used to calculate atomic mass.
