An alpha particle is the nucleus of a Helium atom, with two
protons and two neutrons. An alpha particle has a mass of 6.6 ×
10?27 kg and is accelerated by a voltage of 1.39 kV.The charge on a
proton is 1.60218×10?19 C. If a uniform magnetic field of 0.071 T
is maintained on the alpha particle and perpendicular to its
velocity, what will be particle’s radius of curvature? Answer in
units of m

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...

Carbon-12 contains 6 protons and 6 neutrons. The radius of the
nucleus is approximately 2.7 fm (femtometers) and the radius of the
atom is approximately 70 pm (picometers).
Part A Calculate the volume of the nucleus and the volume of the
atom. (Assume two significant figures.) Express your answers using
two significant figures separated by a comma.
Part B What percentage of the carbon atom's volume is occupied
by the nucleus? (Assume two significant figures.) Express your
answer using two...

A beam of protons traveling at 1.40 km/s enters a uniform
magnetic field, traveling perpendicular to the field. The beam
exits the magnetic field in a direction perpendicular to its
original direction (Figure 1). The beam travels a distance of 1.70
cm while in the field.
What is the magnitude of the magnetic field? Express your answer
in teslas to three significant figures.

1.A neutron in an atomic nucleus is bound to other neutrons and
protons in the nucleus by the strong nuclear force when it comes
within about 1 fm of another particle . What is the approximate
kinetic energy in MeV of a neutron that is localised to within such
a region? Take delta(x)*delta(p) = h/(4pi) and rest energy of
neutron to be 939 MeV. Give your result to 2 significant
figures.
2. What would be the corresponding kinetic energy in...

The diameter of the nucleus is about 11 fm . A simple model of
the nucleus is that protons and neutrons are confined within a
one-dimensional box of length 11 fm .
Part A
What is the first energy level, in MeV, for a proton in such a
box?
Express your answer using three significant figures.
Part B
What is the second energy level, in MeV, for a proton in such a
box?
Express your answer using three significant figures....

A uranium nucleus (mass 238 u , charge 92e )
decays, emitting an alpha particle (mass 4 u , charge
2e ) and leaving a thorium nucleus (mass 234 u ,
charge 90e ). At the instant the alpha particle leaves the
nucleus, the centers of the two are 9.0 fm apart and essentially at
rest.
Find their speeds when they're a great distance apart. Treat
each particle as a spherical charge distribution.
Express your answers using two significant figures....
