Charge is distributed uniformly on the surface of a spherical balloon an insulator . A point particle with charge q is inside. The electrical force on the particle is greatest when A. it is near the inside surface of the balloon B. it is at the center of the balloon C. it is halfway between the balloon center and the inside surface D. it is anywhere inside the force is same everywhere and is not zero E. it is anywhere inside the force is zero everywhere ans E 45. Charge is distributed on the surface of a spherical conducting shell. A point particle with charge q is inside. If polarization effects are negligible the electrical force on the particle is greatest when A. it is near the inside surface of the balloon B. it is at the center of the balloon C. it is halfway between the balloon center and the inside surface D. it is anywhere inside the force is same everywhere and is not zero E. it is anywhere inside the force is zero everywhere ans A Chapter 21 ELECTRIC CHARGE 331 Simpo PDF Merge and Split Unregistered Version - http Chapter 22 ELECTRIC FIELDS 1. An electric field is most directly related to A. the momentum of a test charge B. the kinetic energy of a test charge C. the potential energy of a test charge D. the force acting on a test charge E. the charge carried by a test charge ans D 2. As used in the definition of electric field a test charge A. has zero charge B. has charge of magnitude 1 C C. has charge of magnitude X 10-19 C D. must be an electron E. none of the above ans E 3. Experimenter A uses a test charge qo and experimenter B uses a test charge 2qo to measure an electric field produced by stationary charges. A finds a field that is A. the same in both magnitude and direction as the field found by B B. greater in magnitude than the field found by B C. less in magnitude than the field found by B D. opposite in direction to the field found by B E. either .
