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. (d1.0) d2 Part A Given what we know about this situation, what is the sign of the yellow particle's charge? O positive O negative Submit Request AnswerPart D Now imagine you're told that the magnitude of the yellow particle's charge is equal to 2qblue and 0 = 40. Given this and everything else you know about the situation, calculate the charge qred of the red particle. Express your answer in units of C rounded to three significant figures. AEQ ? qred = Submit Request Answer Part E In no more than 100 words, briefly explain the logic you used to answer the previous question. Note: Please do NOT write out all of the details of your calculation. Instead, describe the physics principles and logical way in which you applied them to arrive at your solution.
