Exploring Coulomb's Law Concepts

What is Coulomb's Law primarily used to describe?

• The gravitational force between two masses

• The electric force between two charged objects

• The magnetic force between two magnets

• The nuclear force within an atom

What is the unit of electric charge?

• Newton

• Joule

• Coulomb

• Watt

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

Compare the forces described by Coulomb's Law and Newton's Law of Universal Gravitation. Which statement is true?

• Both forces are inversely proportional to the square of the distance between objects.

• Both forces are directly proportional to the square of the distance between objects.

• Coulomb's Law applies to masses, while Newton's Law applies to charges.

• Both forces are independent of distance.

Which of the following is an application of Coulomb's Law?

• Calculating the force between two planets

• Determining the force between two electric charges

• Measuring the speed of light

• Calculating the energy of a photon

How does Coulomb's Law differ from gravitational force in terms of the types of charges or masses involved?

• Coulomb's Law applies to neutral objects, while gravity applies to charged objects.

• Coulomb's Law applies to charged objects, while gravity applies to masses.

• Both apply only to charged objects.

• Both apply only to massive objects.

What happens to the force between two charges if one charge is negative and the other is positive?

• The force is repulsive

• The force is attractive

• The force is zero

• The force is doubled

In what scenario would Coulomb's Law be most applicable?

• Calculating the force between two magnets

• Calculating the force between two charged particles in a vacuum

• Calculating the force between two planets

• Calculating the force within an atomic nucleus

How does the electric force between two charges compare to the gravitational force between two masses of the same magnitude?

• Electric force is generally much weaker than gravitational force.

• Electric force is generally much stronger than gravitational force.

• Both forces are generally equal in magnitude.

• Both forces are independent of the distance between objects.
