A micro-transporter moves from one side of an evacuated chamber to another. It is powered by equal-magnitude, opposite-sign charges Q and -Q on top of two station points, as shown in (Figure 1). The transporter's mass is 1.0 g and it is carrying a positive charge of 9.0 x 10-10 C. The figure shows a micro-transporter located between two stations on a horizontal surface.
