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...

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...
