Is it possible for the electric field between two positive charges to equal zero along the line joining the two charges? Yes, but only if the two charges are equal in magnitude. Yes, regardless of the magnitude of the two charges. No, a zero electric field cannot exist between the two charges. This cannot be determined without knowing the separation between the two charges.

Yes, regardless of the magnitude of the two charges.

Which of the following statements are true for electric field lines? Check all that apply. -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 close together in regions of space where the magnitude the electric field is weak and are father apart where it is strong. -Electric field lines can never intersect. -Electric field lines are continuous; they do not have a beginning or an ending.

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 can never intersect.

The strength of the electric field at a certain distance from a point charge is represented by E. What is the strength of the electric field at twice the distance from the point charge? At twice the distance, the strength of the field is E/2. At twice the distance, the strength of the field is 4E. At twice the distance, the strength of the field remains equal to E. At twice the distance, the strength of the field is 2E. At twice the distance, the strength of the field is E/4.

At twice the distance, the strength of the field is E/4.

Which of the following statements are true? In a uniform electric field, the field lines are straight, parallel, and uniformly spaced. Electric field lines near negative point charges circle clockwise. The electric force acting on a point charge is proportional to the magnitude of the point charge. Electric field lines near positive point charges radiate outward. The electric field created by a point charge is constant throughout space.

In a uniform electric field, the field lines are straight, parallel, and uniformly spaced. The electric force acting on a point charge is proportional to the magnitude of the point charge. Electric field lines near positive point charges radiate outward.

When a point charge of +q is placed on one corner of a square, an electric field strength of 2 N/C is observed at the center of the square. Suppose three identical charges of +q are placed on the remaining three corners of the square. What is the magnitude of the net electric field at the center of the square? The magnitude of the net electric field at the center of the square is 0 N/C. The magnitude of the net electric field at the center of the square is 2 N/C. The magnitude of the net electric field at the center of the square is 6 N/C. The magnitude of the net electric field at the center of the square is 8 N/C. The magnitude of the net electric field at the center of the square is 4 N/C.

The magnitude of the net electric field at the center of the square is 0 N/C.
