Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Constants
In the early years of the 20th century, a leading model of the structure of the atom was that
of the English physicist J. J. Thomson (the discoverer of the electron). In Thomson's
model, an atom consisted of a sphere of positively charged material in which were
embedded negatively charged electrons, like chocolate chips in a ball of cookie dough.
Consider such an atom consisting of one electron with mass m and charge -e, which
may be regarded as a point charge, and a uniformly charged sphere of charge +e and
radius R.
Part A
Is equilibrium position of the electron at the center of the nucleus.
O Yes
O No

v Correct
Part B
In Thomson's model, it was assumed that the positive material provided little or no resistance to the motion of the electron. If the electron is displaced from equilibrium by a distance r less than R, find the net force
on the electron.

A simple and common technique for accelerating electrons is shown in the figure, which depicts 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 pass through. Randomized Variables E = 2.7 × 104 N/C Calculate the horizontal component of the electron's acceleration if the field strength is 2.7 × 104 N/C. Express your answer in meters per second squared, and assume the electric field is pointing in the negative x-direction as shown in the figure.

Coulomb's Law A thin rod of length L, oriented in the x-direction, has charge +Q. The rod lies on the floor. The left end of the rod is touching a wall. On the floor, a small frictionless puck of mass M and charge Q is also touching the wall. The puck is a distance b from the left end of the rod. If the wall were removed, the puck would slide at an angle. But the wall constrains the puck to slide only in the y-direction. Here, the y-direction is not vertical. It's along the floor, perpendicular to the rod. a. What is the puck's acceleration, immediately after it's released? Hint: The wall constrains the puck to accelerate only in the y-direction. Therefore, you need to worry only about the y-directed forces. If you can't complete the math, that's OK; but set things up completely. Top down view Base of wall Puck b. What normal force does the wall exert on the puck when the puck is first released? Hint: The normal force, which points in the x-direction, must cancel the x-component of the…
