If ε o = 8.85 x 10 -12 , what is the electric field in between the plates? a. 67.8 MV/m b. 67.8 kV/m c. 56.7 MV/m d. 56.7 kV/m 2. What is the potential difference between the two plates in question 1? a. 34 V b. 340 V c. 34 kV d. 34 MV 3. If E is the electric field between two metal plates separated by a distance d, the potential difference between the plates is 4. A conductor carries a charge Q coulombs and its potential is V volts. The capacitance of the conductor is a. (Q + V) F b. Q/V F c. QV F d. V/Q F 5. If now more charges are added to the conductor in question 4, 6. The capacitance of a capacitor depends on 7. When 3.0 µ C charge is given to a capacitor, the potential difference between the plates is 2.0 V. What is the capacitance of this capacitor? a. 6.0 µ F b. 3.0 µ F c. 1.5 µ F d. 0.15 µ F 8. If the distance between the plates of a parallel plate capacitor is doubled,
