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. Figure The left station has charge plus upper Q. The right station has charge minus upper Q. The transporter carries positive charge q. The transporter is 6.0 millimeters from the left station and 36.0 millimeters from the right station. +Q Station ( + Station 6.0 mm 36.0 mm
