2. Charge by Induction: Two neutral metallic spheres, one on the right and the other on the left, are touching each other. A positively charged glass rod is brought near the sphere on the left (but not close enough to touch), and then the spheres are separated. After the glass rod is removed... a.) Is the left sphere carrying a positive, negative, or neutral charge? b.) Is the right sphere carrying a positive, negative, or neutral charge? c.) If the...

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...

Metal spheres 1 and 2 are touching. Both are initially neutral. The charged rod is brought near without touching the spheres. The charged rod is then removed. The spheres are separated by an external agent. Afterward, the charges on the spheres are: Q_1 is + and Q_2 is +. Q_1 is + and Q_2 is - Q_1 is - and Q_2 is +. Q_1 is - and Q_2 is -. Q_1 is 0 and Q_2 is 0. Explain your choice:...

III. Spheres +0 Two neutral conducting spheres, A and B, are supported by insulating stands. The spheres are touching each other, and a particle (for example, a pith ball) with a positive +Q charge is brought near sphere A as shown i. Is there a net force on the particle with the+ charge at this time? Explain. Without touching the metal spheres, the person holding the base of sphere B now pulls it 4 centimeters to the right. ii. Is...

Prelab Lessons associated with this experiment: Lessons #2, #3 1. We charge a metal sphere with a positive charge. Now we move an neutral metal sphere, which is well insulated from ground, so that it is close to, but not touching the charged sphere. Draw a charge diagram that shows the charge distributions on both spheres. 2. We again charge a metal sphere with a positive charge. Now we ground a second sphere and, keeping it grounded, we move it...
