Question

1.

(a) What kind of motion(s) does an electric charge undergo in a
uniform electric field? Con- sider the possibilities;

(launched from rest, launched with velocity along the field,
launched with velocity against the field, launched with velocity
perpendicular to the field, & launched with velocity components
both against and perpendicular to the field.)

(b) What kind of motion(s) does a charged particle undergo in a
magnetic field? Consider the possibilities;

(launched from rest, launched with velocity purely perpendicular to
the field, launched with velocity components perpendicular to and
along the field. hint: in one case it might not do anything)

(c) What are the ‘magic’ rules for the resistor, capacitor and inductor? What is the current in each?

(d) For a capacitor C with voltage V (t), what is the expression for Maxwell displacement current?

Do charges released from rest always move along electric field
lines; i.e., does the charge stay on the E field line at which it
started?
b) Based on your answer to a), would charges released with an
initial velocity always move along electric field lines?
c) Using kinematic quantities like position, velocity, and
acceleration as well as the concept of a force to describe the
general character of the motion of a [+] charge in motion near a
single [+]...

An electron moving with a velocity of 3.0 x 10^6 m/s enters an
electric field of magnitude 1000 N/C. The electric field is
parallel to the motion of the electron. How far does the electron
travel before it comes to rest?

Your friend sets up a uniform electric field (in units of
N/C):
E (x,y)=−1400i^−4800j^
a. What do you predict you will measure to be the voltage
difference for the displacement going from position (-26,-25) to
position (-28,-45) with distances measured in centimeters?
b. Your friend resets the electric field. This time you need to
figure out the components of the field yourself. You measure the
voltage difference along the positive xx direction to be 2000 V
across a distance of...

a) There is a uniform electric flux perpendicular to a circular
region of radius R = 2.8 cm. The electric flux is only
contained within the circular region, and the total value can be
expressed by the following function: ΦE =
6.3t, where ΦE is in V⋅m when
t is in seconds. At a radial distance of 4.9 cm from the
center of the circle, what is the magnitude of the induced magnetic
field? Express your answer in fT (femtoteslas)....

1. A particle of positive charge q and mass m
enters parallel uniform electric and magnetic fields (of magnitudes
E and B, respectively) both directed in the +z direction with a
velocity v = v0i
perpendicular to both fields.
(a) What is the the particle’s initial acceleration? You can
give your answer as a vector in component form.
(b) What is the radius of the particle’s path (looking down the
z-axis) if the magnetic field is B =
Bk? Does...

An electron enters a region of uniform electric field with an
initial velocity of 70 km/s in the same direction as the electric
field, which has magnitude E = 48 N/C. (a) What is the speed of the
