Problem-Solving Strategy: Coulomb’s Law SET UP 1. As always, consistent units are essential. With the value of k given earlier, distances must be in meters, charges in coulombs, and forces in newtons. If you are given distances in centimeters, inches, or furlongs, don’t forget to convert! When a charge is given in microcoulombs, remember that 1 micro C = 1 m. C = 10 -6 C SOLVE 2. When the forces acting on a charge are caused by two or more other charges, the total force on the charge is the vector sum of the individual forces. If you’re not sure you remember how to do vector addition, you may want to review Sections 1. 7 and 1. 8. It’s often useful to use components in an x-y coordinate system. As always, it’s essential to distinguish between vectors, their magnitudes, and their components (using correct notation!) and to treat vectors properly as such. 3. Some situations involve a continuous distribution of charge along a line or over a surface. In this book, we’ll consider only situations for which the vector sum described in Step 2 can be evaluated by using vector addition and symmetry considerations. In other cases, methods of integral calculus would be needed. REFLECT 4. Try to think of particular cases where you can guess what the result should be, and compare your intuitive expectations with the results of your calculations.

Problem-Solving Strategy: Electric Field Calculations SET UP 1. Be sure to use a consistent set of units. Distances must be in meters, charges in coulombs. If you are given cm or n. C, don’t forget to convert. 2. Usually, you will use components to compute vector sums. As we suggested for problems involving Coulomb’s law, it may be helpful to review Sections 1. 7 and 1. 8. Use proper vector notation; distinguish carefully between scalars, vectors, and components of vectors. Indicate your coordinate axes clearly on your diagram, and be certain that the components are consistent with your choice of axes. SOLVE 3. In working out directions of vectors, be careful to distinguish between the source point S and the field point P. The field produced by a positive point charge always points in the. direction from source point to field point; the opposite is true for a negative point charge. REFLECT 4. If your result is a symbolic expression, check to see whether it depends on the variables in the way you expect. If it is numeric, estimate what you expect the result to be and check for consistency with the result of your calculations
