PROBLEM A 5.00-uC point charge is at the origin, and a point charge q2 = -2.00 µC is on the x-axis at (3.00, 0) m, as in Figure 16.8. (a) If the electric potential is taken to be zero at infinity, find the electric potential due to these charges at point Pwith coordinates (0, 4.00) m, (b) How much work is required to bring a third point charge of 4.00 uC from infinity y (m) to P? (0, 4.00) STRATEGY For part (a), the electric tial at P due to each charge can be calculated from V kg/r. The electric potential at P is the sum of these two quantities. For part (b), use the work-energy theorem, together with Equation 16.5, recalling that the potential at infinity is taken to be zero. poten- 71 Figure 16.8 (Example 16.4) The elec- tric potential at point P due to the point charges q and q, is the algebraic sum of the potentials due to the individual charges. 41 92 (3.00, 0)
