3. The diagrams below in Figure P3 are from an online site called The Physics Class- room. They are used there to illustrate one way to charge objects by induction rather than contact. They show two spheres that are mounted on stands. (a) What is happening in Diagram ii as a negatively charged balloon is brought near one of the spheres? (b) In order for this process to work, the spheres need to be metal while the stands could be rubber, plastic, or possibly wood but should not be metal. Why? (c) Why does the balloon have to be present in Diagram iii? ass (d) In Diagrams iii and iv, the negative charge on the second sphere is shown evenly spread out. Is that correct? Diagram i.

A charged particle moves through a velocity selector at constant velocity. In tire selector, E=1.0104NC and B = 0.250 T. When the electric field is turned off, tire charged particle travels in a circular path of radius 3.33 mm. Determine the charge-to-mass ratio of the particle.
A simple and common technique for accelerating electrons is shown in Figure 18.55, where there is a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. (a) Calculate the acceleration of the electorn if the field strength is 2.50104 N/C. (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.

The direction of the electric field shown in each part of Figure 24.5 is that produced by the charge distribution in the wire. Justify the direction shown in each part, using the Coulomb force law and the definition of E = F/q, where q is a positive test charge.
The discussion of the electric field between two parallel conducting plates, in this module states that edge effects are less important if the plates are close together. What does close mean? That is, is the actual plate separation crucial, or is the ratio of plate separation to plate area crucial?
Integrated Concepts (a) A 0.140-kg baseball, pitched at 40.0 m/s horizontally and perpendicular to the Earth's horizontal 5.00105T field, has a 100-nC charge on it.

An electron is accelerated by a constant electric field of magnitude 300 N/C. (a) Find the acceleration of the electron. (b) Use the equations of motion with constant acceleration to find the electrons speed after 1.00 108 s, assuming it starts from rest
Study Figure 23.3 and the accompanying text discussion of charging by induction. When the grounding wire is touched to the rightmost point on the sphere in Figure 23.3c, electrons are drained away from the sphere to leave the sphere positively charged. Suppose the grounding wire is touched to the leftmost point on the sphere instead. (a) Will electrons still drain away, moving closer to the negatively charged rod as they do so? (b) What kind of charge, if any, remains on the sphere?
Unreasonable Results 64. (a) Calculate the electric field strength near a 10.0 cm diameter conducting sphere that has 1.00 C of excess charge on it. (b) What is unreasonable about this result? (c) Which assumptions are responsible?
