Electric Charge Interactions

What are electric field lines?

• Imaginary lines that represent the direction and strength of the electric field around a charged object.

• Lines that represent the flow of electric current.

• Lines that indicate the shape of an electric field.

• Lines that connect positive and negative charges.

How are electric field lines drawn?

• Electric field lines are drawn to represent the shape of the electric field.

• Electric field lines are drawn randomly without any specific pattern.

• Electric field lines are drawn perpendicular to the direction of the electric field.

• Electric field lines are drawn to represent the direction and strength of the electric field.

What do electric field lines represent?

• The path of electric current

• The shape of the electric field

• Direction and strength of the electric field

• The temperature of the electric field

What is the direction of electric field lines?

• Towards positive charges and away from negative charges

• Away from positive charges and towards negative charges

• Towards positive charges and towards negative charges

• Away from positive charges and away from negative charges

Do electric field lines ever intersect? Why or why not?

• Yes, they can intersect because electric field lines are three-dimensional.

• Yes, they can intersect because electric field lines are one-dimensional.

• Yes, they can intersect because electric field lines are two-dimensional.

• No

What is the significance of the density of electric field lines?

• The density of electric field lines represents the amount of charge in the electric field.

• The density of electric field lines represents the direction of the electric field.

• The density of electric field lines represents the strength of the electric field.

• The density of electric field lines represents the temperature of the electric field.

How can you determine the strength of an electric field using field lines?

• By measuring the length of the field lines.

• By counting the number of field lines.

• By analyzing the color of the field lines.

• By observing the density of field lines.

What is the relationship between the distance between field lines and the strength of the electric field?

• Exponential

• No relationship

• Inverse

• Direct

What types of charges repel?

• Positive and Positive
• Positive and Neutral
• Negative and Neutral
• Neutral and Neutral
