10. Two uncharged metal ball, X and Y, stand on glass rods. A third ball Z carrying a positive charge, is brought near ball Y. A conducting wire is then run between X and Y. The wire is then removed, and ball 2 is taken away. When this is all done what will be the sign of the charges on balls x and Y? Explain your reasoning

1. Three identical metallic conducting spheres carry the following charges: q1 = +4 20 μο q2 +740 μο and q3 -600 μ . The spheres that carry the charges qi and q2 are brought into contact. Then they are separated. After that, one of those two spheres is brought into contact with the third sphere that carries the charge q3; those two are then separated as well a) What is the final charge on the third sphere? x(4.66e-17) C 2....

Open-Response Homework Problem 2.2 Consider the following experiment with a positively charged rod and two identical conducting spheres: Step I: A positively charged rod is brought near, but does not touch, two identical conducting spheres in contact, where one of the spheres is closer to the rod than the other Step 11: One of the spheres is grounded, and then the connection with ground is broken. The spheres remain in contact through this process. Step I: The rod is removed....

Bob places a neutrally charged conducting ball next to a large, charged plate. The conducting ball is weakly attracted to the plate. What is the net charge on the plate? 1. a) Positive b) Negative c) Neutral (i.e., zero charge) d) Either positive or negative, but it is impossible to tell which A +1 C charge is at the origin, and a second +1 C charge is at position (x,y)-(2 m, 0). How much work is required to move the...

A red blood cell typically carries an excess charge of about -2.5 times 10-12 C distributed uniformly over its surface. The red blood cells can be modeled as spheres approximately 7.0 mu m in diameter and with a mass of 9.0 times 10-14 kg. How many excess electrons does a typical red blood cell have? Does the mass of the extra electrons appreciably affect the mass of the cell?...
