A point charge ?1 with a charge 2.0 X 10−6 C is initially at rest at a distance of 0.25 m from second charge ?2 with a charge 8.0 X 10−6 C and mass 4.0 X 10−9 kg. Both charges are positive. Charge ?1 remains fixed at the origin, whereas ?2 travels to the right upon release. a) Determine the speed of charge ?2 when it reaches a distance of 0.50 m from ?1 Diagram posted below.

Ch 18 q3 In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin gold foil. 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. The alpha particle has a charge of +2e and the gold nucleus a charge of +79e. Suppose that an alpha particle is initially a great distance from the gold, has a kinetic energy of 4.20 MeV (4.20 106 eV), and is headed directly at a gold nucleus. How close will the particle come to the center of the nucleus? Treat the nucleus and the alpha particle as point charges.
