Let's now turn our attention to point charges and the forces they exert on each other. In particular, the following diagram shows a configuration of three point charges that we'll be analyzing. Here's what we know about this situation: . The blue particle is fixed to the origin of the coordinate system and has a positive charge qblue = 1 C, . The red particle is fixed at the point (5.1 cm, 0 cm) and has some unknown charge qred, and . The yellow particle is fixed at the point (7.5 cm cos 0, -7.5 cm sin 0) and has some unknown charge qyellow- We also know that the net electric force on the blue particle has a magnitude 1 N and is directed in the -y direction.
