Question

Two 10 cm diameter charged disks face each other, 27 cm apart. The left disk is charged to - 50nC and the right disk is charged to + 50nC . What is the electric field , both magnitude and direction, at the midpoint between the two disks? Express your answer to two significant figures and include the appropriate units. B) A) To the Left disk B)To the right disk C) Parallel to the plane of the Disks. C) What is the force F on a -1.1 nC charge placed at the midpoint? Express your answer to two significant figures and include the appropriate units. D) A) To the Left Disk B) to the right disk C) parallel to the plane of the Disks

Explanation / Answer

Before we do any computations on this problem, let's analyze the problem a little bit. We need to know the net force acting upon the middle of the three charges. Visualizing this problem, we see that q2 will have a pull in the positive x-direction on q1 and so will q3, because q2 will pull on q1 with its negative charge and q3 will push on q1 with its positive charge. Thus the direction must be along the positive x-axis. Secondly, we can apply coloumb's law, since we have multiple electric c
