Question

Which of the following statements are true for electric field lines?

a. Electric field lines are close together in regions of space where the magnitude of the electric field is strong and are farther apart where it is weak.
b. Electric field lines can never intersect.
c. At every point in space, the electric field vector at that point is tangent to the electric field line through that point Electric field lines are close together in regions of space where the magnitude of the electric field is weak and are farther apart where it is strong.
d. Electric field lines point away from positive charges and toward negative charges.
e. Electric field lines are continuous; they do not have a beginning or an ending.
f. At every point in space, the electric field vector at that point is perpendicular to the electric field line through that point.

Answer 1

True statements regarding electric field lines are that they are closer in strong-field regions, never intersect, are tangent to the electric field vector, point from positive to negative charges, and are continuous.

Step-by-step explanation:

The statements concerning electric field lines that are true include the following:

• Electric field lines are close together in regions of space where the magnitude of the electric field is strong, and they are farther apart where it is weak.
• Electric field lines can never intersect.
• At every point in space, the electric field vector at that point is tangent to the electric field line through that point.
• Electric field lines point away from positive charges and toward negative charges.
• Electric field lines are continuous; they do not have a beginning or an ending.

It is important to note that field lines are a visual tool used to represent the electric field, and they convey information about the direction and magnitude of the field at various points in space. Their spacing indicates the field strength, and their direction is indicative of the electric field vector at any point.
