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 5.70 MeV (5.70 106 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.
Two hard rubber spheres, each of mass m = 14.9 g, are rubbed with fur on a dry day and are then suspended with two insulating strings of length L = 5.25 cm whose support points are a distance d = 3.06 cm from each other as shown in the figure below. During the rubbing process, one sphere receives exactly twice the charge of the other. They are observed to hang at equilibrium, each at an angle of 0 = 10.4° with the vertical. Find the amount of charge on each sphere. (Enter your answers from smallest to largest.)

A small metal sphere, carrying a net charge of qt= +7.5 mC, is held in a stationary position by insulating supports. A second small metal sphere, with net charge of 2' +3 mC and mass 2 g is projected toward q . When two spheres are 0.8 m apart, sa is moving toward qt with speed 22.0 mls, see Figure. Assume that the two spheres can be treated as point charges. Neglect the force of gravity. a) What is the speed ofqt when the spheres are 0.5 m apart† How close can q2 approach to q1 ?
The dipole moment of the water molecule (H2O) is 6.17×10−30C⋅m. Consider a water molecule located at the origin whose dipole moment p⃗ points in the positive x direction. A chlorine ion (Cl−), of charge −1.60×10−19C, is located at x=3.00×10−9 meters. Assume that this x value is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. Find the magnitude of the electric force, ignoring the sign, that the water molecule exerts on the chlorine ion.

Identical 42 μC charges are fixed on an x axis at x = ±3.4 m. A particle of charge q = –20 μC is then released from rest at a point on the positive part of the y axis.
