Electrostatics - Physics

Front

What is electrostatics?

Back

Electrostatics is the branch of physics that studies electric charges at rest and the forces and fields associated with them.

Front

What is the principle of conservation of charge?

Back

The principle of conservation of charge states that the total electric charge in an isolated system remains constant over time.

Front

What happens when two like charges are brought close to each other?

Back

Like charges repel each other.

Front

What happens when two opposite charges are brought close to each other?

Back

Opposite charges attract each other.

Front

What is the unit of electric charge?

Back

The unit of electric charge is the coulomb (C).

Front

What is the formula for calculating the electrostatic force between two charges?

Back

The electrostatic force (F) can be calculated using Coulomb's Law: F = k * |q1 * q2| / r^2, where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric charges to flow freely through it.

Front

What is a conductor?

Back

A conductor is a material that allows electric charges to flow freely through it.

Front

What is charging by friction?

Back

Charging by friction occurs when two different materials are rubbed together, causing electrons to be transferred from one material to the other.

Front

What is charging by induction?

Back

Charging by induction is the process of charging an object without direct contact, by bringing a charged object close to it, causing a redistribution of charges.
