Electric Charge & Coulomb's Law

Front

What is electric charge?

Back

Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It can be positive or negative.

Front

What are the two types of electric charge?

Back

The two types of electric charge are positive charge (e.g., protons) and negative charge (e.g., electrons).

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the electrostatic force between two charged objects. It states 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 happens to the electrostatic force when the distance between two charges is halved?

Back

The electrostatic force increases by a factor of four, as it is inversely proportional to the square of the distance.

Front

What is the formula for Coulomb's Law?

Back

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

Front

What type of force exists between two electrons?

Back

A repulsive force exists between two electrons because they both have negative charge.

Front

What type of force exists between an electron and a proton?

Back

An attractive force exists between an electron and a proton due to their opposite charges.

Front

If an atom loses an electron, what type of charge does it have?

Back

The atom becomes positively charged.

Front

What is the relationship between charge and force according to Coulomb's Law?

Back

The electrostatic force increases as the magnitude of the charges increases.

Front

What is the effect of doubling one charge in a two-charge system?

Back

Doubling one charge will double the electrostatic force between the two charges.
