Coulomb's Law

What two factors does Coulomb's Law depend on?

• The size of the charges and the distance between them.

• The temperature and pressure of the environment.

• The mass of the charges and the velocity of the charges.

• The electric field strength and the magnetic field strength.

If each of the charges is doubled, what happens to the force?

• The force remains the same.

• The force doubles.

• The force quadruples.

• The force halves.

What happens to the force if one charge is halved?

• The force is doubled.

• The force is halved.

• The force remains the same.

• The force is increased by 50%.

What happens to the force if the distance between two charges is doubled?

• The force is reduced by 1/4.

• The force remains the same.

• The force is doubled.

• The force is reduced by 1/2.

What is Coulomb's Law?

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

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

• Coulomb's Law states that the force between two charged objects is independent of the distance between them.

• Coulomb's Law states that the force between two charged objects is directly proportional to the sum of the magnitudes of the charges and inversely proportional to the distance between them.

If the force is 10 N at a distance of 2 m, what will it be at 1 m?

• 20 N

• 30 N

• 40 N

• 50 N

What is the effect of increasing both charges by a factor of 3 on the force?

• The force increases by a factor of 6.

• The force increases by a factor of 8.

• The force increases by a factor of 9.

• The force remains the same.

What happens to the force if the distance between two charges is halved?

• The force doubles.

• The force remains the same.

• The force quadruples.

• The force decreases by half.

What is Coulomb's constant (k)?

• 8.99 x 10^9 N m²/C²

• 6.67 x 10^-11 N m²/C²

• 9.81 m/s²

• 3.00 x 10^8 m/s

How can Coulomb's Law be applied in real-world scenarios?

• To calculate the forces between charged particles in physics, chemistry, and engineering applications.

• To determine the speed of light in a vacuum.

• To measure the temperature of a substance.

• To analyze the structure of atomic nuclei.
