Understanding Coulomb's Law and Electric Force

What is required for an electrostatic force to exist between two particles?

• The particles must be at rest.

• The particles must be in motion.

• The particles must be charged.

• The particles must be neutral.

How is the direction of the electric force between two charged particles represented?

• With a triangle.

• With a circle.

• With a square.

• With an arrow.

What does the symbol 'K' represent in Coulomb's Law equation?

• The distance between particles.

• The mass of a particle.

• The charge of a particle.

• The constant of proportionality.

In Coulomb's Law, how does the force between two charges change if the distance between them is doubled?

• The force doubles.

• The force is halved.

• The force is quartered.

• The force remains the same.

Which of the following is an example of an inverse square law?

• Ohm's Law

• Newton's First Law

• Hooke's Law

• Coulomb's Law

How does the electric force differ from the gravitational force?

• Electric force can only attract.

• Gravitational force can repel.

• Electric force can attract or repel.

• Gravitational force acts only on charged objects.

What is the main similarity between the equations for electric and gravitational forces?

• Both involve the mass of objects.

• Both involve the charge of objects.

• Both are inversely proportional to the square of the distance.

• Both are directly proportional to the square of the distance.

Which constant is used in the equation for gravitational force?

• C
