towards

Question 6

Dipoles. (positive charge and negative charge)

Answer 6

Case 1: Attractive

Question 7

Dipoles. (positive charges)

Answer 7

Case 2: Repulsive

Question 8

Dipoles. (negative charges)

Answer 8

Case 3: Repulsive

Question 9

Three Basic Rules in Drawing Electric Field Lines

Answer 9

1) Field lines emanate from the positive charge and terminate to the
negative charges.

2) Field lines do not intersect at one point. Field lines only meet if
the force between the charges is attractive.

3) The density of the lines (number of lines per space) represents the
strength of the field.
