The figure shows two uncharged metal balls, X and Y, supported
on insulating stands. A third ball, Z, carrying a negative charge,
is brought near the first two. A conducting wire is then run
between X and Y. The wire is then removed, and ball Z is finally
removed. When this is all done it is found that:
Options: (choose the correct one)
a) ball X is — and ball Y is +
b) balls X and...

A couple of small insulating balls are attached by separate .25 m threads. The balls are identical and the threads are attached to a common point on the ceiling. The mass of each ball is .00080 kg. Initially the balls are uncharged and hang straight down. They are then given the same positive charges and, as a result, spread apart with an angle of 36o between the threads. a. Determine the distance between the two balls after they are charged....

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

a) You're holding a small metal ball suspended on a piece of insulating string from the ceiling. You and the ball are both initially electrically neutral. A positively charged rod is brought near to the metal ball; you then let go of the metal ball. You now have a positive electric charge. This process is called charging by 1.) Electroscope. 2.) Insulation. 3.) Conduction. 4.) Induction. b) Charged glass and plastic rods hang by threads. An object attracts the glass...

2) Three identical metal spheres are supported on insulating stands and are all neutral at the start of the experiment. Then: sphere 2 makes contact with sphere 1 while sphere 1 is close to a charged plexiglass rod. Contact is then broken with the rod in place. Sphere 2 touches sphere 3 and both spheres are taken to another part of the lab where the force between them is measured to be 0.002 N when their centers are 10 cm...
