Which statement is FALSE regarding the Pearson Mastering homework assignment?  

Two points, a and b, are located in the x-y plane, with coordinates given in meters (m), as shown in the figure. A uniform electric field of magnitude 5000 V/m is directed along the +x axis. A charged particle with charge Q = + × 10-4 C is moved from point a to point b by an external force. The particle starts and ends at rest. How much work does the external force do on the particle (in J)? Note: The result may be positive or negative.

Three point charges are fixed in the x-y plane, as shown in the figure. The charges are QA = + × 10-4 C, QB = + × 10-4 C, and QC = – × 10-4 C. The (x, y) coordinates of each charge are indicated in the figure, with coordinates given in meters. What is the electric potential energy of the system (in J)?

Three point charges are fixed in the x-y plane, as shown in the figure. The charges are QA = + × 10-8 C, QB = + × 10-8 C, and QC = - × 10-8 C. The (x, y) coordinates of each charge and of a point P are indicated in the figure, with coordinates given in meters (m). What is the electric potential at point P (in V)?

Two points A and B are shown in the x-y plane with coordinates given in meters (m). A uniform electric field of magnitude V/m points in the +x direction. Given that the electric potential at point A is 100 V, determine the electric potential at point B (in volts). Note: The result may be positive or negative.

A small charged particle with mass × 10-6 kg is held at rest in a uniform electric field that points vertically upward and has magnitude 2 × 105 N/C. After being released, the particle accelerates with acceleration a = 2000 m/s2, as shown in the figure. Determine the charge on the particle (in nC).
