a small metal bead, labeled a, has a charge of 28 nc . it is touched to metal bead b, initially neutral, so that the two beads share the 28 nc charge, but not necessarily equally. when the two beads are then placed 5.0 cm apart, the force between them is 5.0×10−4 n . assume that a has a greater charge.

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
