Document Summary
Please read the problems carefully and answer them in the space provided. Write on the back of the page, if necessary. A charge q1 is positioned on the x-axis at x = a. A charge of +2q is placed at the center of an uncharged conducting shell. What will be the charge on the inner and outer surfaces of the shell, respectively: -2q, +2q, q, +q, -2q, -2q, -2q, +4q. A particle with charge q is at rest when a uniform magnetic field is suddenly turned on. The alpha decay of an atom of u238. A ring of radius 0. 05 m is in the yz plane with its center at the orgin. The ring carries a uniform charge of 10 nc. The electric potential at x=0. 12 m is approximately: 217 v, 543 v, 692 v, 809v, 963 v. A charge +q moves with speed v in a plane perpendicular to a uniform magnetic field b.
