Electric Fields S4

Which of the following statements is false about electric field lines

• electric field lines cannot cross
• electric field lines point away from positive charge
• electric field lines are always straight lines
• electric field lines show how a proton would move in an electric field

At which point is the electric field the strongest

• A
• B
• C
• D

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

Q_A and Q_B are two charges creating an electric field. Based on the electric field lines, we can conclude

• Q_A and Q_B are both positive
• Q_A and Q_B are both negative
• Q_A is positive and Q_B is negative
• Q_A is negative and Q_B is positive

Which of the following is a true statement about the electric field between the two plates?

• The field is attractive between the plates and uniform in strength

• The field is repulsive between the plates and uniform in strength

• The field is attractive between the plates and strongest near the positive

• The field is repulsive between the plates and strongest near the positive

Based on the arrangement of the electric field lines in the diagram, what are the charges?

• both charges are the same

• the charges are opposite

• they are neutral; no charge

Which statement best describes the electric fields in the image?

• The charges are neutral.

• Both charges are negative, so the field lines are alike.

• The field lines move toward a positive charge and away from a negative charge.

• The field lines move away from a positive charge and toward a negative charge.

TRUE or FALSE: The electric field lines for a positive charge is always directed away from the charge.

• 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
