Suppose that one of the two charges in synthesis problem 2 is twice as large as the other one. Use the procedures suggested in parts a and b of synthesis problem 2 for this new situation. (When sketching the field, there should now be twice as many field lines emerging from the larger charge as from the smaller charge.) 

Data From Problem 2

Suppose that two equal positive charges lie near one another, 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.)
