Question

An
electron (mass 9.11x kg) travels at 2x10^5 m/s to the left. A
magnetic field of magnitude 1.2 T points out of the page.

a) What is the force (magnitude and direction) on the
electron?

b) What is the acceleration of the electron?

c) If the magnetic field is uniform in this region, the
electron will follow a circular path. What is the radius of the
circle?

Answer #1

an electron is projected with a velocity of 3 x 10^7 m/s East
into a uniform magnetic field of 4 T downward.
a) find the magnitude and direction of the force on the
electron.
b) what will be the radius of the circular path of the
electron?

1. An electron enters a magnetic field of magnitude 1.75T
directed vertically upward. If the electron’s initial velocity was
4.7x10^6 m/s, what is
a) the magnitude and direction of the magnetic force on the
electron.
b) the radius of its circular path.

An alpha particle travels at a velocity of magnitude 820 m/s
through a uniform magnetic field of magnitude 0.038
T. (An alpha particle has a charge of charge of
+3.2 × 10-19
C and a mass 6.6 ×
10-27 kg) The
angle between the particle's direction of motion and the magnetic
field is 69°.
What is the magnitude of
(a) the force acting on the particle due to the
field,
(b) the acceleration of the particle due to
this force?...

An electron enters a region of space containing a uniform
1.27×10^−5 T magnetic field. Its speed is 157 m/s and it enters
perpendicularly to the field. Under these conditions, the electron
undergoes circular motion. Find the radius ? of the electron's path
and the frequency ? of the motion.

An electron enters a region of space containing a uniform
0.0000149-T magnetic field. Its speed is 121 m/s and it enters
perpendicularly to the field. Under these conditions, the electron
undergoes circular motion. Find the radius r of the electron\'s
path, and the frequency f of the motion.

1. An electron is moving through a magnetic field whose
magnitude is 8.99 × 10-4 T. The electron experiences only a
magnetic force and has an acceleration of magnitude 3.22 × 1014
m/s2. At a certain instant, it has a speed of 8.44 × 106 m/s.
Determine the angle (less than 90o) between the electron's velocity
and the magnetic field.

A particle with a charge of +3e and a mass of 1.7E-21 kg is
traveling right to left and enters a region of space moving at 150
m/s, where a uniform magnetic field exists (see figure). Once in
the field, the charge follows a circular path where r = 45
cm. What is the magnitude and direction of the magnetic field?

An electron moves at 2.70×106 m/s through a region in
which there is a magnetic field of unspecified direction and
magnitude 7.10×10−2 T What is the largest possible
magnitude of the acceleration of the electron due to the magnetic
field IN M/S^2?)

1.
A cylindrical region of space of radius R contains a uniform
magnetic field B with direction into the page. If the magnitude B
inside the cylinder changes in time and outside the cylinder it is
zero, describe the induced electric field (magnitude and direction)
for points inside the cylinder (r < R). Find the magnitude and
direction of the induced electric field at r = 5.00 cm if the
magnetic field changes at a constant rate from 0.500T to...
