Coulomb's Law & Charging

Front

What do electrons do to protons?

Back

Electrons attract protons and have no effect on neutrons.

Front

What happens to the force if the charge on one object is doubled?

Back

The force would double in magnitude but remain in the same direction.

Front

Which statement is NOT true about a charged object and an insulator?

Back

The charged object is grounded.

Front

What exhibits inverse-square behavior?

Back

Light spreading from a bulb, the Sun's gravitational effect on the solar system, and the electric field around a Van der Graaff generator.

Front

What happens to electrons when a negatively charged stick is brought close?

Back

Electrons would flow from A to B.

Front

Define Coulomb's Law.

Back

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

Front

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

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 is an insulator?

Back

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

Front

What is a conductor?

Back

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

Front

What is polarization in the context of electric charges?

Back

Polarization is the separation of charges within an object, causing one side to become more positive and the other more negative.
