Behavior of Charged Particles in Electric Field

What must be the charge of the two particles and how do you know?

• They are both positive, the electric field lines repel each other and are heading out of the charges

• They are both positive, field lines repel each other and are heading toward the charges

• They are both negative, field lines repel each other and are heading out of the charges

• They are both negative, field lines repel each other and are heading toward the charges

How can you determine how strong the electric force a point charge will experience at a certain point in an electric field?

• The total number of electric field lines

• How close together the electric field lines are

• What direction the electric field lines are pointing

• How large the charge at the center is drawn

At which point is the electric field the weakest?

• A because it is the furthest away
• A because the field lines are further apart
• C because the field lines are further apart
• C  because it is the furthest away

The electric field lines for a positive charge is always directed away from the charge. True or False?

• True

• False

What does it mean when the electric field lines are close together?

• the field is positive
• the field is negative
• The field is strong
• the field is weak
