Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

23.25 • Identical point charges 41 and 42 each have positive charge
+6.00 µC. Charge 4, is held fixed on the x-axis at x = +0.400 m, and
92 is held fixed on the x-axis at x = -0.400 m. A small sphere has
charge Q = -0.200 µC and mass 12.0 g. The sphere is initially very
far from the origin. It is released from rest and moves along the y-axis
toward the origin. (a) As the sphere moves from very large y to y = 0,
how much work is done on it by the resultant force exerted by 41 and 42?
(b) If the only force acting on the sphere is the force exerted by the
1 of 1
point charges, what is its speed when it reaches the origin?

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.
