A positive charge Q is placed on a hollow conducting sphere of inner radius R 1 and outer radius R 2 . A particle with charge q is placed at the center of the cavity in the sphere, as shown in the sketch. The magnitude of the electric field in the cavity, at a distance r from the center ( r < R 1 ) is: A. zero B. 2 1 4 R Q C. 2 4 r q D. 2 4 ) ( r Q q + E. ) ( 4 ) ( 2 2 1 r R Q q- + ___ 2. Increasing the separation between the plates of an isolated parallel plate capacitor, for which the charge remains constant: A. increases the capacitance B. increases the potential difference between the plates C. decreases the potential difference between the plates D. increases the electric field between the plates E. does not change the capacitance ___ 3. A series circuit consists of a battery of electromotive force E with internal resistance r and an external resistor R . If R is adjusted, while r and E are kept constant, when R = r the energy dissipated per unit time by the external resistance R is: A. twice that by r D. a minimum B. half that by r E. need to know E to answer the question C. a maximum ___ 4. In Amperes Law, i s d B = , the integration must be over: A. any closed surface D. any closed path B. any surface E. any closed path that surrounds all the current producing B C. any path 2 NAME ______________________________ ___ 5.
