a proton and an alpha particle (a Helium atom stripped of its electrons) are accelerated through an electric potential difference of 20 MV. If the proton and alpha-particle start at rest, then what are their final speeds? answer is 62Mm/s (proton) and 44 Mm/s (alpha particle) .
An alpha particle can be produced in certain radioactive decays of nuclei and consists of two protons and two neutrons. The particle has a charge of q = +2e and a mass of 4.00 u, where u is the atomic mass unit, with 1 u = 1.661 ✕ 10−27 kg. Suppose an alpha particle travels in a circular path of radius 4.60 cm in a uniform magnetic field with B= 1.70 T. Calculate the following values. (a) its speed m/s...
An alpha particle, which contains two protons and two neutrons (i.e., charge of +2e and mass of 4m_p), is accelerated from rest through a potential difference of Delta V = -1000 V prior to entering a region of space that contains a uniform magnetic field of 1.00 mT into the page. Determine the speed of the particle as it enters the magnetic field region. Calculate the force in vector notation that the alpha particle experiences just after it enters the...
