Part A A micro-transporter moves from one side of an evacuated chamber to another. It is powered by equal-magnitude, opposite-sign charges @ and -Q on top of two station If a 7.0 x 10 -N friction force opposes the transporter's motion, what must be the magnitude of @ to make the transporte points, as shown in (Figure 1). The transporter's mass is move with an initial acceleration of 1.0 m/s-? 1.0 g and it is carrying a positive charge of 9.0 x 10-10 C. Express your answer with the appropriate units. ? Q = Value C Figure
