Extra Problem 11:
Consider the diagram below.
The two charges are separated by a distance of 40.0 cm. Q1 has a charge of -3.9 nC and Q2 has a charge of +5.8 nC. Determine the location where the net electric field is 0.0 N/C. Express your answer as a x-coordinate location (in cm), with Q1 being located at x = 0.0 cm and Q2 being located at x = +40.0 cm. See diagram below.

Habits of an Effective Problem Solver
An effective problem solver by habit approaches a physics problem in a manner that reflects a collection of disciplined habits. An effective problem-solver...
- ... reads the problem carefully and develop a mental picture of the physical situation. If necessary, sketches a simple diagram of the physical situation to help you visualize it.
- ... identifies the known and unknown quantities; records them in an organized manner. A diagram is a great place to record such information. Equates given values to the symbols used to represent the corresponding quantity - e.g., Q1 = 2.4 μC; Q2 = 3.8 μC; d = 1.8 m; Felect = ???.
- ... uses physics formulas and conceptual reasoning to plot a strategy to solve for the unknown quantity.
- ... identifies the appropriate formula(s) to use.
- ... performs substitutions and algebraic manipulations in order to solve for the unknown quantity.
