Question

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 6.0×10−10C.

a) If a 4.0×10−3-N friction force opposes the transporter's motion, what must be the magnitude of Q to make the transporter move with an initial acceleration of 1.0 m/s2?

answer:

Answer 1

-ya forces acting on change q is fi, due to change te, due to change -Q & f due to friction Net force is 1 .
