An alpha particle – which is basically a helium nucleus – has a mass of roughly 6.65×10^-27kg and has a net electric charge of +2e.
a: Imagine an alpha particle traveling to the left at 350 km/s enters a region with a .5G magnetic field pointed directly upwards. How strong is the force on the alpha particle?
b: How does the force on the alpha particle change as it moves through the magnetic field? How does that affect the motion of the particle? Assume the magnetic field has a constant strength.

An alpha particle is a nucleus of helium. It has twice the
charge and four times the mass of the proton. When they were very
far away from each other, but headed toward directly each other, a
proton and an alpha particle each had an initial speed of 0.005c,
where c is the speed of light. What is their distance of closest
approach? Hint: There are two conserved quantities. Make use of
both of them. (c = 3.00 × 108...

An alpha particle is a nucleus of helium. It has twice the
charge and four times the mass of the proton. When they were very
far away from each other, but headed toward directly each other, a
proton and an alpha particle each had an initial speed of
4.1×10-3 c, where c is the speed of light. What is their
distance of closest approach? There are two conserved quantities.

A uranium-238 nucleus at rest undergoes radioactive decay,
splitting into an alpha particle (helium nucleus) with mass
6.64×10-27 kg and a thorium nucleus with mass 3.89×10-25 kg. The
measured kinetic energy of the alpha particle is 6.73×10-13 J. If
after the decay, the thorium nucleus is observed to move in the
negative z direction. After the decay, what direction did the alpha
particle move? possible answers: Positive x, Negative x, Positive
y, Negative y, Positive z, Negative z. After the...

A helium nucleus (called an alpha particle) contains 2 neutrons
and 2 protons with no electrons. If any electrons are added, there
is a negligible amount of mass added but obviously one negative
charge per electron is added. Three particles are injected into a
constant B-field of 2T at a velocity of
3×106ms. The first
particle is only the alpha particle
(He++), the second particle is a nucleus
with 1 electron (He+), and the third
particle is a nucleus with...

Could you put the helium nucleus (also known as an "alpha
particle") somewhere on a line between the proton and electron
where it wouldn't feel a net force? Why or why not?

Problem 10.23
An alpha particle (a helium nucleus, containing 2 protons and 2
neutrons) starts out with kinetic energy of 10.0 MeV (10.0 ×
106 eV), and heads in the +x direction straight toward a
gold nucleus (containing 79 protons and 118 neutrons). The
particles are initially far apart, and the gold nucleus is
initially at rest. Answer the following questions about the
collision.
What is the initial momentum of the alpha particle? (You may assume
its speed is small...

An alpha (?) particle is the nucleus of a 4He atom and consists
of 2 neutrons and two protons bound together. Let's take apart an ?
particle, step by step, looking at the energy required at each
step. To do so, we may want to use the following atomic masses: 4He
