An alpha particle with a kinetic energy of 10.0 MeV makes a head-on collision with a gold nucleus at rest. What is the distance of closest approach of the two particles? (Assume that the gold nucleus remains stationary and that it may be treated as a point change. The atomic number of gold is 79, and the alpha particle is a helium nucleus consisting of 2 protons and 2 neutrons).

An alpha particle with a kinetic energy of 12.0 MeV makes a head-on collision with a gold nucleus at rest. What is the distance of closest approach of the two particles? (Assume that the gold nucleus remains stationary and that it may be treated as a point charge. A gold nucleus has 79 protons, and an alpha particle is a helium nucleus consisting of two protons and two neutrons. The mass of an alpha particle is 6.64424 x 10-27 kg....

If the alpha particles have an initial kinetic energy of 7.7 MeV, then assuming a head-collision between an alpha particle (helium nucleus with +2e charge) and a gold nucleus (79 protons, so +79e charge), and using conservation of energy at the point of closest approach when all of the alpha particle's kinetic energy is converted to electric potential energy, calculate the approximate distance of closest approach (and thus coarsely estimate the size of the nucleus)

Problem 10.23 An alpha particle (a helium nucleus, containing 2 protons and 2 neutrons) starts out with kinetic energy of 9.9 MeV (9.9 x 100 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...

In Rutherford's scattering experiments, alpha particles (charge = +2e) were fired at a gold foil. Consider an alpha particle with an initial kinetic energy K heading directly for the nucleus of a gold atom (charge =+79e). The alpha particle will come to rest when all its initial kinetic energy has been converted to electrical potential energy. Find the distance of closest approach between the alpha particle and the gold nucleus for the case K = 3.5 MeV

An alpha particle (a helium nucleus, containing 2 protons and 2 neutrons) starts out with kinetic energy of 10.3 MeV (10.3 times 10^6 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...

The Rutherford scattering formula breaks down (i.e. fails to describe the data) if the incoming alpha particles actually enter the nucleus. Nuclear radii (in meters) have been found to be approximated by the formula R=(1.12x10^-15)A^1/3 where A is the atomic mass number.. Beyond what kinetic energy (in MeV) would an alpha particle scattering off of a Silicon nucleus no longer be described by the Rutherford formula? (Use the formula above for both the Silicon and the Helium nucleus and explore...

Alpha-particle scattering experiments using uranium (Z = 92) as the target material show that the alpha-particles experience a pure Coulomb repulsion only for energies up to 8.8 MeV. Estimate the radius of the uranium nucleus.

Use the following information to answer the next question. In the Rutherford alpha particle scattering experiment, some alpha particles were deflected coming straight back from the gold foil. When an alpha particle is emitted by the radium sample, it has a kinetic energy of 1.0 x 10-22 J. The electric potential energy of a charged particle in a radial electric field is modelled as kq192 Ер r Numerical Response 2. The maximum acceleration of an alpha particle at its closest...

He unexpectedly observed a few of the particles scattered almost directly backward. This result was not consistent with then current models of atomic structure and led Rutherford to propose the existence of a very dense concentration of positive charge at the center of an atom-the atomic nucleus.
