Chapter 26 The Electric Field (The Parallel-Plate Capacitor & Motion of a charged particle in an E-field)

3
E-field of a ring of radius R & charge Q on the z-axis.. E-field of a disk of radius R & charge Q on the z-axis.. E-field of an infinite plane… Last time…

4
Two protons, A and B, are next to an infinite plane of positive charge. Proton B is twice as far from the plane as proton A. Which proton has the larger acceleration? 1. Proton A. 2. Proton B. 3. Both protons have the same acceleration. Quiz Question 1

5
At the dot, the y-component of the E-field due to the shaded region of charge is 1. 2. 3. 4. 5. Quiz Question 2

6
A sphere of charge Q and radius R (uniformly charged or a spherical shell) has an E-field of the form… Exactly the same as that of a point charge! E-field of a sphere..

7
Two electrodes, one with charge +Q and the other with –Q, placed face-to-face a distance d apart.. 26.5: The Parallel-Plate Capacitor

8
What’s the E-field between the plates? What’s the E-field outside of the plates? The Parallel-Plate Capacitor +++++++++++++++++++++++++++++++ -------------------------------------------------------

9
What’s the E-field between the plates? What’s the E-field outside of the plates? The Parallel-Plate Capacitor ------------------------------------------------------- +++++++++++++++++++++++++++++++

10
is the same in magnitude and direction at every point in space. Parallel-plate capacitors produce uniform E-fields Uniform E-Field…

11
The E-field exerts a force on a charged particle… If it’s the only force acting on q, then… If it’s a uniform E-field, then… 26.6: Motion of a Charged Particle in an E-Field

12
Two 6.0 cm diameter electrodes are spaced 5.0 mm apart. They are charged by transferring 1.0 x 10 11 e - s from one electrode to the other. An e - is released from rest at the surface of the negative electrode. How long does it take the e - to cross to the positive electrode? What is its speed as it collides with the positive electrode? Assume the space between the electrodes is vacuum. i.e. 26.8: An e - moving across a capacitor
