Chapter 12, Problem 2SP

Suppose that two equal positive charges lie near each other, as shown in the diagram.

a.    Using small arrows, indicate the direction of the electric field at the labeled points on the diagram. Think about the direction of the force that would be exerted on a positive charge placed at each of these points.

b.    By drawing an equal number of field lines emerging from each charge, sketch the electric field lines for this distribution of charge. (See the diagrams in section 12.4.)
