- Three charges are arranged as shown with distance d = 44 cm. What is the potential energy change when the 55 µC charge moves straight up a distance d so that it is straight across from the 33 µC charge? 33 μC d d -77 µC -55 μCCh 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.Points B [at (4,-5) m] and C [at (3, 5) m] are in a region where the electric field is uniform and given by E=-5i-+4j N/C.
