- One charge freely moves away from another charge. The force between the two charges changes while the total energy is constant. True FalseAnswer Enet and qGreenA positively charged rod is brought near a metal electroscope that is initially uncharged. As shown in the figure, the rod does not touch the electroscope. There is no charge transfer between the electroscope and rod, but the leaves of the electroscope move apart from each other when the rod is brought near the top of the electroscope. Which one of the following choices is the best explanation for this phenomenon? + + + + + + electroscope O Protons are repelled by the rod into the leaves of the electroscope. Electrons are attracted out of the leaves of the electroscope toward the rod. Protons are repelled into the leaves of the electroscope and electrons are attracted out of the leaves of the electroscope. O Positively charged electrons are repelled by the rod into the leaves of the electroscope. O Positively charged electrons are repelled into the leaves of the electroscope and regular electrons are attracted out of the leaves of the electroscope.Particles A and B collide to produce particles C, D, and E: A+B ---> C +D+E.

A charge of -1.5 uC is transferred from point a to point b as shown in the figure. Determine: a) The change in electrical potential energy b) If the -1.5 uC charge has an initial velocity of zero. What is its final velocity if it has a mass of 5.0 x 10-15 kg?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.11:05 < Back E_M_HW-2.pdf Dashboard +q 000 000 Calendar a 3 Pra 4) Four charges are an equal distance r from some origin. What is the direction of the electric field, E, at the origin, due to the four charges? Then what is the magnitude of E at the origin.
