    1. ABoth forces are attractive.
    2. BBoth forces are repulsive.
    3. CThe gravitational force is repulsive and the electrostatic force is attractive.
    4. DThe gravitational force is attractive and the electrostatic force is repulsive.
  10. 10Suppose a positive charge of +20e is moved through a small opening in a hollow metal sphere and placed at a point P, which is connected to the inside of the sphere by means of a metal wire (see figure).
    (a) What is the final charge distribution?
    (b) Is there any limit to the amount of charge that can be transferred in this way, if the sphere is in a vacuum, so that there is no way for the charge to leak off?
    Imagem da pergunta 10

    2. Ba. +20e at point P
    3. Ca. +20e spread on the surface of the sphere, mostly at the bottom
    4. Da. +20e spread on the surface of the sphere, mostly at the top
    5. Eb. yes
    6. Fb. no
