Question

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...

An alpha particle (a He nucleus, containing two protons and two
neutrons and having a mass of 6.64×10−27 kg ) traveling
horizontally at 34.8 km/s enters a uniform, vertical, 1.08 T
magnetic field.

In the form of radioactive decay known as alpha decay,
an unstable nucleus emits a helium-atom nucleus, which is called an
alpha particle. An alpha particle contains two protons and
two neutrons, thus having mass m=4u and charge q=2e. Suppose a
uranium nucleus with 92 protons decays into thorium, with 90
protons, and an alpha particle. The alpha particle is initially
moving at velocity= 5.89 *10^8, and the radius of alpha particle is
r=3.1* 10^ -11.What is the speed of...

a helium atom, with a charge of 2e and a mass of 6.6 ×
10 to the -27 kg, is accelerated by a voltage of 3200 Volts in a
uniform magnetic field of 0.240 T. A) what is the speed of the
helium atom? B) what is the radius of curvature of the helium atom?
C) what is the helium atom's period of revolution?

A bare helium nucleus consists of two protons and two neutrons
and has a mass of 6.64 × 10–27 kg
Calculate its kinetic energy in joules at 2.00% of the speed of
light. Use the non-relativistic formula.
What is this in electron volts?
What voltage would be needed to obtain this energy?

1)
Consider two stable isotopes, helium-3 and helium-4. How many
neutrons and protons are there in each isotope? What are the mass
numbers?
Solution - Helium - 3 has 2 protons and 1
neutron. Mass number = 3
Helium - 4 has 2 protons and 2 neutrons . Mass number = 4
