Electric Charge and Electric Field

An uncharged object has:

• more protons

• more electrons

• equal number of protons and electrons

• no protons and electrons

Where an electric charge experiences a force, there is an:

• Electric Field

• Magnetic Field

• Electric Current

• Gravitational Field

We are led to believe that there were two kinds of charge because we are able to:

• isolate them in separate containers

• see two effects, attraction and repulsion

• detect different weights for the same object

• separate electrons and protons.

Which of the following objects are attracted by a positively charged object?

• only positively charged objects

• only negatively charged objects

• only neutral objects

• all of the bove

The force that holds atoms together is:

• magnetic

• gravitational

• electric

• unknown to scientists

In Coulomb's Law, the relationship of Force and distance of the charges is directly proportinal.

• TRUE

• FALSE

When an object has an imbalance in the number of electrons and protons, it is electrically charged.

• TRUE

• FALSE

The direction of an electric field is away from a negative charge and toward a positive charge.

• TRUE

• FALSE

In Coulomb's Law and even in getting the Energy in Electric field, K is equal to 9x10⁹ N-m²/s².

• TRUE

• FALSE

Coulomb’s law relates the force between two single charges separated by a distance.

• TRUE

• FALSE
